1) All specifications are given for Pockels cell load of 6 pF.
2) Heat sink temperature must not exceed 35°C (95°F) in all regimes of operation.
SYNC1 and SYNC2 are used for 2-pulses control operation mode. HV program input amplitude is readout at SYNC2 rising edge and is used to set HV output amplitude for next HV output pulse which is started with SYNC1 rising edge. SYNC is used for single pulse control mode. HV program input amplitude is readout at SYNC falling edge and is used to set HV output amplitude for next HV output pulse which is started with SYNC rising edge.
Green trace – modulated analog input signal, purple trace - trigger signal SYNC (single pulse control mode), yellow trace - HV pulse.
High Voltage drivers with Fast Amplitude Modulation (FAM) are designed to form laser pulse trains or even single laser pulses with specific user-defined amplitude levels while this driver controls operation of Pockels cell in the pulse picker system.
DPS/DPD-FAM series drivers allow to control the amplitude of each HV output pulse. The control is realized by one (DPS model) or two (DPD model) trigger-sync pulses and analog input amplitude control or modulation.
DPS/DPD-FAM drivers capability to modulate the amplitude of ultrafast laser pulses can be successfully employed in some materials processing applications.
