1)  The Pockels cell voltage defines the wavelength on which the system  operates. Thus in a simple half-wave scheme the voltage amplitude in kV  roughly corresponds to wavelength 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 available 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 available 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
