Pockels Cell Driver Head
The core of our Pockels cell driver heads are high performance solid state switches. All driver heads are EMC tested to suite medical applications as well as research applications. They are available in one of our standard housing as well as in any specifically designed housing which suits your specific needs. The Pockels Cell is mounted in a separate compartment on top of a four or five-axis alignment table. Usually the Pockels cell is integrated into the driver head, detachable Pockels cell compartments can be designed as well. Beam height varies from 28mm to 80mm but any custom height can be fabricated upon customer request.
Main Features:
- high repetition rate
- fast switching, on and off
- variable pulse duration
- double pulses with spacing < 30ns
- low jitter
- for BBO, RTP, KD*P CdTe Pockels cells
- true square pulse shape

General Specifications
max. operating voltage | up to 22kV 1 |
max. repetion rate | 20MHz continuous, up to 50MHz in burst mode 1 |
optical rise- and falltime | 200ps – 7ns 1 |
output load | 50 Ohm or capacitive |
pulse width | any |
on / off – ratio | 0 < 1 |
jitter, input to output | < 100ps |
trigger input impedance | 50 Ohm |
trigger input | 3 – 10V, width > 50ns |
1 These specifications are mutually dependent, i.e. reprates of 20MHz are achievable at switching voltages of 1kV, at 10kV repetition rate may be limited to about 700kHz. Higher switching voltage tends to increase rise time. For a burst mode switch maximum average pulse frequency must be observed
