5.8 A CW / 15.7 A Pulsed Laser Diode Driver

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

The PCX-7420-B offers the capability of providing both QCW (pulsed), and CW (DC) outputs. It can serve as a CW driver at currents from 0.050 A to 5.8 A, and as a pulsed/QCW driver at currents from 3 A to 21.5 A. Furthermore, the output may be biased to any CW current from 3 A to 5.8 A, then pulsed above this bias current at up to 15.7 A maximum. A new feature allows the bias current to be pulsed and triggered independent of the main current trigger.
