Chapter 5 Operation Guide
(7) Set the desired power from Pin1 ~ 8;
(8) Set Pin18 to H level and turn on MO;
(9) Wait for 5ms;
(10) Fast modulation of the laser by Pin19. Enter the H / L level to control the
laser on and off. The rise / fall time of the laser switch has been limited (see
Chapter 4 for detailed specifications). The speed of modulation cannot be
faster than the sum of rise and fall times. Typical rise / fall time is 250us, and
its modulation period should be greater than 500us (corresponding frequency is
2kHz);
(11) After completing the operation of the laser switch and waiting for the next
task, if the time exceeds 20ms, it is recommended to turn off the MO, which will
reduce power consumption, extend the life of the MO, and avoid the residual
power output of the MO;
(12) Turn off BS and MO after completing a task (Pin18 and Pin19 are set to L
level)
(13) Disconnect the 24VDC power supply.
2.Job characteristics
(1) During laser operation, PRR can be changed through Pin20. When changing
the PRR, please note that the time between two adjacent rising edges must not
be greater than the cycle time of the lowest PRR frequency. For a laser with
a minimum repetition frequency of 20kHz, it should not be greater than 50us.
Otherwise, the protection circuit will automatically add missing pulses. If the
PRR is greater than the specified maximum repetition frequency, the protection
circuit limits it to the maximum value.
(2) It is allowed to change the power settings of Pin1 ~ 8 during laser operation
and store it in the laser. The laser will respond to the changed power setting
during the specified rise time.
(3) If Pin18 is at H level and Pin19 is at L level, there will be laser output below
20mW working wavelength.
(4) If the temperature of the laser module e 45 ° C, the laser will
automatically turn off, and at the same time at Pin16 and
