Figure 23 Laser Running Status Monitoring
1) Status Monitoring
Pump indicator light: Monitor whether the pump of the laser is currently in normal working
state, which is green under normal conditions, and red light if abnormal alarm occurs.
PA 、 MO 、 Red indicator light: Monitor the control signal. Green light means signal is
effective(high level), and red light means signal is not effective(low level).
D0-D7 indicator light：Monitor the current power signal of the laser, corresponding the 8-bit
binary mode, D0 is the lowest and D7 is the highest. Green light means this pin signal is
effective(high level), and red light means this pin signal is not effective(low level).
PRR/kHz and PULSE/ns : Monitor the actual laser working frequency and pulse width.
Pump temperature: Monitor the temperature of optical module.
Power current: Monitor the secondary drive current value of the laser.
TEC temperature: Monitor the current seed source temperature.
System parameter: Internal system parameter setting interface.(For JPT internal use only)
Log record：To record the laser setting and alarm.
Alarm record：To record the sequence of the latest 10 laser alarms.
2)Alarm description
Board tempLT: The board temperature is lower than the set temperature.
Board tempOT: The board temperature is higher than the set temperature.
Pump tempLT: The pump temperature is lower than the set temperature.
