OVERVIEW

We are honoured b y your c hoice of a Data logic produc t, spec ificall y a new product belonging to the VlaseTM product fam ilies, which aim to satisf y new market evolutions, and especially the integrat ion industrial laser sources.

OPERATION OF A LASER SYSTEM WITH GALVANOMETRIC SCANNING

The laser generates a train of high-energy pulses of invisible radiation. In order to obtain a mor e accur ate focus, t he laser beam is f irst enlarged using an optica l expans ion s ystem and then deflected by a scanning system consisting of two mirrors mounted on galvanometric motors. These mirrors deflect the beam in a controlled beam along the X and Y axes; processing of the product surface occurs by coordinating the movement of the two motors with the turning on/off of the laser beam. The deflected laser beam is focused by an F-Theta objective before it hits the surface of the product. Generally speaking, the marking is carried out within the focus of the beam.

MARKING SOFTWARE

The marking software Lighter is preinstalled on the system.
NOTE:
Consult Lighter software user’s manual for a proper use of the same.
NOTE:
Consult the proper Appendix to upgrade the preinstalled software if necessary.
The VlaseTM laser marking system features a control unit whose size is compatible with the standard 19” 2,5U in varnished steel, a nd a resonator whose compact dimensions make it eas y to integrate into a s ystem that comprises safet y devices required by applicab le regulations, the management of m arking signals and the customer’s complementary modules, if any.
All laser marking system connections are found on the rear of the rack: power supply, safety, electrical signals, communication ports, patch cord to the scanner head, while the front features key and enable command devices, status LED in addition to a USB connector for the communication with the internal embedded controller.

4.5 THERMALI ZATION AND SUPPRESSION OF GIANT PULSES

Thermalization is useful in order to obtain a good marking quality.
To obtain uniform markings and work processes is im portant to keep Nd:YVO4 crystal constantl y pumped. This operation is calle d thermalization and is im plemented supplying t he laser diode with a suita ble level of current. In this way a cert ain amount of pumping radiation at 808nm exc ites the crystal “but being the Q­switch closed” no laser radiation is emitted by the system.
TM
With the Vlase
Software thermalization
Software thermalization is implemented automatically by the Lighter marking software and consists in defining, within the m arking project, a certain thermalization l evel at which the crystal is maintaine d during the non-emission intervals. It is generally recommended to keep the level of therm alization similar to the power level used for the marking or slightly lower.
source, this procedure can be implemented using Software Thermalization.
Figure 62: Temporal diagram of S oftware Thermalization.
USE AND OPERATION
67
Operation in
(CW)
As you can see in the graph shown i n the Figure, during the m arking phas e the Q-Switc h Modulation s ignal determines the frequency with which the laser pulses are generated, the effect of the LEVEL signal is a corresponding change in the laser diode current.
Please note that, in order for this to occur, the EMISSION signal has to be active.
NOTE:
Please also note that the c urrent supp lied to the laser dio de is intentio nall y forced to have ris ing and falling times in the range of 150us . This protection from fast commutations (generate d either from fast changes of LE VE L s ig nal or f r om EMISSION signal fr ont) is i nten de d t o red u c e damage risk and extend lifetime of the diode itself
During the thermali zation phas e, the EMI SSION s ignal sta ys active, while the LEVE L signal goes into a pre­set thermalization level (i.e. 90%) and the Q SW MOD signal stays fixed at 0 V.
At the end of the therm alization phase, befor e starting another m arking phase, the FPK ( First Pulse K illing) procedure needs to be impl emented i n order to discha rge the cr ystal, thus avoidi ng the gen eration of “giant” pulses which may cause marking defects as well as damages to the internal optics of the resonator.
.
To discharge the crystal, the Q-Switch is kept closed (Q SW MOD signal at 0 V) and t he E MIS SION signal is brought to a 0V level for at least 450 microseconds, so as to cut off the current in the laser diode and consequently the pumping of the crystal (FPK delay).

LASER RADIATION

Laser radiation is an electromagnetic emission with a micrometric wa velength which ranges from the long infrared (CO ultraviolet (excimer laser). It should be considered non-Ionizing Radiation. In Vlase stimulated by “optical pum ping” generated by a Diode Las er. The continuous ref lection of Photons, between a front mirror and rear mirror, c reates a positive reaction so that their number continues to incre ase, until reaching the concentr at ion nec ess ary to produce a beam which projects fr om the s emi-reflecting front m ir ror . The radiation (whic h we can imagine as a “Beam of in visible light”) is then Collimated a nd Focalized with Lenses at a point where the intensity becomes high enough to be able to react with various materials producing an alteration in them due to thermal effect. The radiations of Vlase entirety without using t he natur al defens e pro vided b y pupil ref lex! Added to th is is the fac t that it is gener all y very intense, with the result that it can be very harmful to the eye and present vision problems.
To prevent permanent damage to vision, a few precautions must be taken. All individuals who m a y be ex posed to da ngerous lev els of laser rad iation , m ust kno w that the laser is act ive and wear protective goggles if necessary.

WARNING!
Directly viewing a laser bea m can cause irreversible damage to vision.
Due to its high power, the laser integrated in the Datalogic system provokes reflected las er light from flat surfaces. Reflected light is potentially dangerous for the eyes and skin. Electromagnetic emission with a micrometric wave length is placed in long infrared, and is therefore invisible, thus it is not clear where reflected beams are aimed.
WARNING!
It is indispensable to protect yourself from reflected light beams, because they can be
sufficiently intense to create permanent injury to the eyes or skin
In addition to possible injur y to the e yes or sk in, direc t laser em ission can c ause flam m able materials to bur n like organic solvents (alcohol, acetone) or gasoline and cause fabric and clothing to burn.

WARNING!
This marking system is classified as Class 4. Class 4 includes lasers which can produce ris ks, not only from direct or reflected radiation, but also fr om scattered rad iation! The laser s ources m ay be a significant risk for the skin and risk of burning flammable materials
.

ABSORPTION OF LASER RADIATION

Human skin absorbs electromagnetic radiation in different ways depending on the wave length of the radiation. Both the eye an d skin have a “predisposition” for accepting certain wave lengths, and ar e more unresponsive to absorbin g others. In the specific c ase of the Eye, the Corn ea and Crystalline l ens let all the wave lengths from 400 to 1 400 nm pass and reach the Retin a, even with various attenuations. T hey include the range from visible light to IR A inf rared. T hus Nd: YVO this range and leads to direct Retina exposure! In terms of the Skin, the “biological window” has different absorption percentages but is not dissimilar in terms of wave length. The maximum exposure values for Skin are much different compared to those tolerated by the Eye.
laser radia tion ( 355 nm wavelength) is incl uded in

Figure 72: Eyeball section.
In terms of the damage m echanism that absorbed ra diation can cause, i t also depends on the wave length. Short lengths (ultraviolet: UV-C 18 0-280nm; UV-B 280-315 nm , UV-A 315-400 nm) generall y cause photo­chemical effects:
cataract, or opacification of the crystalline lens
melanic coloring, or reddening of the skin
Greater wavelengths (inf rared: I R-A 780-1 400 nm ; I R-B 1400 3000 nm; IR-C 300 0-10 thermal effects:

The degree of injury obviously depends on the amount of absorbed radiation and the instantaneous power of the radiation source.

CLASSIFICATION AND DANGER LEVEL

Regulations have esta blished different classes of Las er danger based on the ability to injur e people, from Laser Class 1 (basically safe in all conditions) to Laser Class 4 dangerous in vario us condi tio ns .
Lasers which can produce risks, not only for direct or reflected radiation, but also for scattered radiation belong to Class 4. These Laser sources can also have a significant risk for the Skin and fire risk for flammable material. For these reasons, the User m ust put into effect all measures aim ed at containing the radiation to make sur e that it is term inated at the end of its useful path. The oper ator mus t also be informed of the risks from exposure to Laser radiation and mus t wear specific I.P.D. (individual pr otection devices) including goggles that protect against radiation and are certified as suitable for this use.
WARNING!
The VlaseTM marking system contains a Class 4 invisible laser source.

RADIATION VIEWING CONDITIONS

The laser output b y th e resonator is to be c ons ider ed as a hi ghly collimated and i ntens e monochromatic lig ht source. Due to thes e c har acteristics it can be s e en as a “ point source” of h igh l um inos i t y. T his means that its image is then focalized on t he R et ina in a very small spot with a danger ous ly high power density! If the beam becomes divergent and sc atters to a non-reflecting sc reen, then there is an “extended v ision” of the image, with a decisively less dang erous power density. So there are differ ent types of radiation viewing based on the access to the radiation and consequently different degrees of dangerousness.

DIRECT VIEWING OF THE LASER BEAM

This type of viewing is t he most dangerous and can occur at the outlet of the laser aperture after ha ving removed the lens. It is to be avoided at all costs ! No protective goggles repre sent a valid means against direct viewing of the beam.

DIRECT VIEWING OF THE BEAM AFTER MIRROR REFLECTION

This may occur by directing the beam on a reflecting surface. Viewing of a mirror reflected beam from a flat surface is very dangerous and equal to direct viewing.

DIRECT VIEWING OF THE BEAM OUTPUT BY AN OPTICAL FIBER

This happens if an O ptical Fiber disc onnects from the resonator. View ing of the beam is dangerous up to a significant distance. Filters and Goggles do not ensure safety.

DIRECT VIEWING OF THE BEAM AFTER FOCUSING

This occurs if the laser beam is not extinguished with an opportune absorber at the end of its useful path . Looking at the beam is dangerous up to a co nsiderable distance. Filters and goggl es can ensure safet y for brief exposure, as long as they are the right size and certified.

SCATTERED VIEWING OF THE BEAM AFTER FOCUSING

This is the m ost frequent viewing, but opp ortune Filters and Goggles can ensure safety, even for prolon ged exposure.
The Nominal Ocular Hazard Distance (N.O.H.D.) for Vlase™ are showed in the next paragraph.
WARNING!
Always use goggles with conformity certificate. Remember that no goggles can provide prolonged protection from direct or mirror-reflected
radiation

N.O.H.D. DETERMINATION AND O.D. OF PROTECTION GOGGLES

In order to determinate the characteristics of the protection goggles, it is essential to determine the characteristics of the radiation, knowing its optical path, the dimensions of the beam and its divergence.
In particular, it is very impor tant to know the real divergence of the beam in output f rom the objective (F­Theta). With all these optical data it is possible to calculations of the Nominal O cular Hazard Distance (N.O.H.D.) and of the optical density (O.D.) requested to the protection filters of the laser radiation.
Calculations have been done following the CEI EN 60825-1 (2014) Normative regarding nominal distance and optical risk in the worst condition and in case of accident exposure o f 10 seconds for direct radiation and 100 seconds for diffused radiation.
