Precision Pulse Control

The PCX-7420 is an air-cooled, high-powered CW/QCW current source designed to drive diode lasers, bars, and arrays. The pulsed output current is adjustable from 3.0 A to 21.5 A. The pulse width is adjustable from 50 ns to 500 ms, and the rise time is under 25 ns. The pulse repetition rate is selectable from 40 to 100,000 Hz when using the internal pulse source, and from single-shot to 1 MHz when using an external source.

The PX-7420 provides both QCW (pulsed) and CW (DC) outputs. It can serve as a CW driver at currents from 3.0 A to 5.8 A, and as a pulsed/QCW driver at currents from 3.0 A to 21.5 A. Furthermore, the output may be biased to any CW current from 0.050 A to 5.8 A, then pulsed above this bias current up to 15.7 A maximum. A new feature allows the bias current to be pulsed and triggered independently from the main current.
