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 |
Optional units:可選單位:
OG8(12)/1(10)-2 :2-channel system driving single Pockels cell by two HV pulses. Perfect for injection/ejection in solid-state fs amplifiers.
OG8/100 :Up to 100 kHz repetition rate, external water cooling is needed (the value of dissipated thermal power at 100 kHz is approximately 80 W).
OG55/20 :Up to 20 kHz repetition rate, external water cooling is needed (the value of dissipated thermal power at 20 kHz is approximately 40 W).
