4.5 Control Modes
4.6 Entering a Control Mode
Fiber Delivered Direct Diode Laser User Guide 1500W
There are two different modes of operation-CW and modulation. In the CW mode, the laser
emits continuously, and you can set the output power by percentage of output power. In the
modulation mode, the laser emits in a waveform of pulses. The pulse can be set by upper
computer.
We provide three modes to control the product-hyper terminal, RS-232 and AD. The hyper
terminal mode is a local control mode; RS-232 and AD mode are remote control modes. In the
hyper terminal mode and RS-232 mode, you can set all the parameters in the CW or
modulation mode, but in the AD mode, the output power is controlled by input analog signal,
and the emission is controlled by input modulation signal.
We have sensors to monitor the operation conditions of the laser, if any abnormal condition
occurs, the laser will be stopped, and error information will be sent out from the RS-232 port.
The following diagram shows the process of entering a certain control mode.

You can enter the operation mode by pressing corresponding number on the keyboard.
Press ‘1’ in the mode selection page, you will enter ‘CW mode’. In this mode, the laser emission
is continuous, so just one parameter needs to be set-percentage of output power.
Then type a number between 0 and 100, with minimum increment of 1, then press ‘Enter’.
For example, type ‘20’ and enter, the output power will be set to approximate 20%.
Because the output power is not linear with the power setting signal, so it is not accurately
present by percentage of output power.
If you don’t input anything, the system will accept 0 as the default, which means that if you
press ‘Enter’ without no value typed in, the percentage of output power will be set to 0%

power to 60%.
The repetition frequency is between 50Hz and 50kHz, but you must input a number between 50
and 50000, so for 2kHz, input 2000;
Duty cycle is between 0% and 100%, for 50%, type in 50;
For 60% output power, type in 60;
If you input a value out of the range specified in the brackets, the system will instruct you again
to input a legal value. Just follow the instructions.
When the parameters are set and laser emission is enabled (‘LASER’ on front panel is pressed

4.8.3 The Operation in RS-232 Mode
Fiber Delivered Direct Diode Laser User Guide 1500W
Before you start the laser, check the wiring, cooling connection and the most important, the
delivery cable and optic terminal are OK. Make sure that the interlock is shorted, and the laser
emission button is up (emission disabled). Then start the chiller.
Turn the key to ‘REM’ position to start the laser, and system start self-check. If the interlock is
not shorted or the ‘LASER’ button is pressed down, the system self-check cannot pass. In this
condition, you must power off the laser, and deal with the problem, then start the laser again.
The systems self-check will pass in about 30 seconds, after that, you can send codes from the
upper computer. In RS-232 mode, the laser emits on conditions that the ‘Emission On’ code (1B
4F 0D) is received, operation parameters are set and remote modulation signal inputs from
‘MOD’.
In RS-232 mode, you can still use hyper terminal to monitor the status of the laser. All you have
to do is to start windows hyper terminal, and configure it as stated in 4.7.2 Hyper Terminal
