5055SC-B Q-switch Driver Modules are intended for driving Pockels cells in q-switch applications. The driver incorporates a self-contained high voltage power supply and only requires +24 Volts DC input. High voltage is adjusted to the required level by either a single turn locking pot or with optional VC 0- 5V "voltage control" input. Triggering is from any conventional TTL pulse sources. Repetition rates from single shot to 1kHz are attained with the standard HV Pulse Module. The 5055SC-B incorporates an EMI/RFI shielded enclosure with HV insulated output wires terminated with 2mm pin terminals.
The 5055SC-B features a balanced output, i.e., there are 2 independent output connections, one for each terminal on the Q-switch/Pockels cell. The Switched and Fixed HV outputs have identical HV DC levels which produce a static, zero net differential voltage across the crystal. This prevents cumulative ion migration damage which occurs in KD*P crystals when exposed to continuous DC voltage. When triggered, the Switched side goes to ground; the Unswitched side remains at HV resulting in a voltage pulse across the terminals.
Q-switch drivers have a single fast switching circuit "switch" and provide a fast leading edge or rise time. In q-switch applications QWV (Quarter wave voltage) is applied to a Pockels cell when the driver is triggered. Another common applications at HWV to clip one edge of pulse laser to shorten the laser pulse width. Applications requiring >5KV require our model 5056SC-A-8 or 5048SC drivers which provide higher max voltage.
5055SC-B Optional ACCESSORIES: MW4024F: AC to +24VDC miniature converter with BNC termination mates to the driver provides the required +24 VDC power input. Rated: 40W, 1.6A
MG-CL38 Gimbal tilt mount for Pockels cells with 35mm diameter housings such as our Series Q1059, 1150 and 1147 models and many industry standard cells. See Fig 2. FastPulse Technology family of Q-switch Driver Modules are compatible with KD*P, RTP, and BBO Q-switches.
KD*P Pockels cells are the most common type offering lowest cost and largest aperture options. (Series Q1059, 1145, 1148, CF1043 and 1144) Our most popular models which include 8mm up to 30mm apertures. See our series 1147 RTP and 1150 BBO Pockels cells for other optical performance characteristics.
