4320-QCW Laser Controller 20A
The 4320-QCW LaserSource provides up to 20A of current, and is the highest current offered in the 4300 series. When your application demands up to 20A of current, the 4320-QCW is an excellent choice as a low cost, high value solution. The 4320-QCW supports both CW and Quasi-CW (QCW) mode.

Simple User Interface
The 4320-QCW’s user interface is remarkably simple… so easy to use, you’ll have it up and running in no time. Unlike other instruments which rely on 7-segment LED displays and a confusing array of indicators and buttons, the 4320-QCW instead presents the information on a high contrast VFD display in an easy-to-read format. The 4320-QCW displays current, voltage, and photodiode current simultaneously… no need to toggle though the readings like on most instruments. Settings and error messages are in clear English, not cryptic codes and flashing status lights.

Quasi-CW (QCW) Mode
The 4320-QCW adds QCW mode, a feature not found in most other laser drivers in its class. Many applications require the low duty cycle, high current pulses that QCW offers to manage thermal loading on the device. With rise times of less than 50µs, and pulse widths as narrow as 100µs, the 4320-QCW offers an effective and low-cost QCW solution. If you are looking for the non-QCW driver, see the 4320 LaserSource.
