Operation timing charts
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.
Example of driver operation
Green trace – modulated analog input signal, purple trace - trigger signal SYNC (single pulse control mode), yellow trace - HV pulse.
Features:
- Fast amplitude modulation of HV pulses
- Output HV pulses amplitude range from 0.1 to 2.5 kV
- HV pulses repetition rate up to 500 kHz
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.
DP-FAM series drivers allow to control the amplitude of each HV output pulse. The control is realized by one or two trigger-sync pulses and analog signal for amplitude modulation (HV program).
DP-FAM driver capability to modulate the amplitude of ultrafast laser pulses can be successfully employed in materials processing applications.
