Sicherheitshinweise
Je nach Betriebsart emittieren diese Bauteile hochkonzentrierte, nicht sichtbare Infrarot­Strahlung, die gefährlich für das menschliche Auge sein kann. Produkte, die diese Bauteile enthalten, müssen gemäß den Sicherheits­richtlinien der IEC-Norm 60825-1 behandelt werden
Features
Laser bar mounted on passive mount, no water required
For continuous wave (cw) and quasi continuous wave (qcw) operation
Highly reliable semiconductor material with minimum life time of 10,000 h, typically >50,000 h
Low thermal resistance
Low smile (< 2.5 μm) and low mechanical tolerances
Applications
Pumping of solid state lasers
Direct industrial applications (soldering, surface treatment,…)
Medical applications
Printing applications
Safety Advices
Depending on the mode of operation, these devices emit highly concentrated non visible infrared light which can be hazardous to the human eye. Products which incorporate these devices have to follow the safety precautions given in IEC 60825-1 “Safety of laser products”.

2)
Die zentrale Emissionswellenlänge muss beim spezifizierten Strom kontrolliert werden. Liegt die Wellenlänge höher als im Testprotokoll spezifiziert, so weist dies auf einen schlechten thermische n Kontakt und eine thermische Überlastung der Laserdiode hin. Bevor der Laserbetrieb weitergeführt wird, muss der thermische Kontakt verbessert werden. Die zentrale Emissionswellenlänge schiebt mit 0,28 nm/K. Check the emission wavelength at the specified current. A much longer wavelength than specified in the test protocol indicates inefficient or inadequate cooling and thermal overload of the diode laser. Then the cooling has to be improved before continuing laser operation. The emission wavelength shifts with 0.2 8 nm/K.
3)
Das Anlegen einer Spannung in Sperrrichtung der Laserdiode muss ausgeschlossen werden. Reverse voltage has to be excluded.
