Q-Drive™ OEM Pockels Cell Driver
A cost-effective, high-performance Pockels cell driver for incorporation into Q-switched laser systems.
Full Product Description- Pulse voltage :
- Min: 1.5 kV, Max: 4.5 kV
- Pulse width :
- Min: 200 ns
Product description
This driver has a repetition rate from 1–4.5 kHz, an output voltage of 1.5–4.5 kV, rise and fall times of 4–7 ns with pulse widths of 150 ns–5 μs.
The driver is packaged on a compact 100x83 mm (4x3¼") circuit board. The driver is fully self-contained with the power supply and all control circuitry, needing only 24 VDC and a trigger signal to operate.
Designed for reliability with low component stress and worst-case design margins, the driver meets specifications from –40C to +70C. It works with loads to 30 pF.
