(1) - energy ratio of a picked and any non-picked pulse. The given contrast values are valid for adjacent pulses. Actual contrast with DKDP crystals is defined by piezoelectric ringing effect and depends on exact operational parameters. The contrast is better when the duration of HV pulse is shorter and HV pulse amplitude is lower. (2) - when operating with 1 Hz…2 MHz input pulse train， an external trigger signal must be used. Such a signal must lead the optical pulse by 0.25-3 us， must be rigidly in sync with the pulse to be picked and must have jitter of less than 200 ps; (3) - the HV generator unit requires cooling to support operating temperature below 35°C. Water cooling is required when operating at output frequency of 10 kHz and more (water flow 1 L/min， water temp. 20-22°C， tap or building-scale supply may be also be used if permitted). Heating power to be dissipated does not exceed 80 W even at the highest frequencies (a water chiller is not included and may be supplied separately).
