DSM Series, Differential Switch Mode Pulser, for system integration
DSM-Series: Universal pulser for capacitive loads (e.g. pockels cells) in full bridge configuration with ~3 ns to 6 ns electrical transition time and variable pulse width from 4 ns to infinite. The unit consists of two push-pull switches (half-bridge circuits), which are turned on by an internally generated phase-shifted signal, where by phase 1 is given by the leading edge and phase 2 by the trailing edge of the control pulse. The pulse width of the HV pulse across the capacitive load corresponds with the time difference of the shifted signals respectively with the pulse width at the control input. For capacitive load only. Very compact design for placement directly at the pockels cell. Available with cooling options CF, GCF, ILC and DLC for high power operation.
