1) The Pockels cell voltage defines the w***elength on which the system operates. Thus in a simple half-w***e scheme the voltage amplitude in kV roughly corresponds to w***elength in hundreds of nm, i.e. if you require

the system for 800 nm you are looking for a ~8 kV unit, 1064 nm – 10 kV etc. ARC can be then done according to your request.

2) The optical train rep. rate is first optionally divided by a prescaler of either 1/16/256/4096 and then by a compulsory divisor of an integer from range of 2 to 65535 to get the desired output frequency. The unit also

provides burst and single-shot modes. There is also an additional external electric TTL trigger connection ***ailable for control of output pulse frequency. See CU specs for more details.

3) Proper operation with input train rep. rate 1 Hz…2 MHz is only ***ailable with triggering by external signal. The external trigger signal must lead the optical pulse by 0.25-3 μs and must be strictly locked to the optical

train with jitter less than 200 ps

4) Value of dissipated thermal power for OG8/25 and OG88/1 is approximately 25 W, for OG8/50 around 50 W
