* For Advanced, Express and Specific line: Delay and jitter are specified for the case of triggering by the pulse with the certain duration determined by the manufacturer (typ. 800-900 µs). Counted from the fall edge of the trigger pulse. In case of triggering with rise edge, the delay is about 800-900 µs and the jitter is approx. 2% of it.


1Measured at 1 kHz pulse repetition rate.
2 Triggering with external electric pulse generator; generator is not included in delivery set.
3 Generation of periodical laser pulses using PC, step 0.01 kHz. Average energy may be changed by software from 10% up to maximum value.
4 Generation of periodical laser pulses at fixed rep. rate; external generator and/or PC are not required.
5 Sync Out signal is generated by pulse of laser light.
6 Depending on pulse repetition rate. Fan Heat Sink to be attached depending on operation conditions and/or pulse repetition rate operation range.
