4302-QCW Laser Controller 2A
The 4302-QCW LaserSource is the lowest current range in the 4300 LaserSource family, with the lowest noise and highest accuracy. Intended for use with higher power pump modules and other devices needing up to 2A of current, the 4302-QCW supports both CW and Quasi-CW (QCW) mode.


 

High Compliance
The 4302 features a high 15V compliance for higher voltage applications, such as LED testing or quantum cascade lasers, as well as excellect performance with lower voltage laser diodes.


 

Simple User Interface
The 4302-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 4302-QCW instead presents the information on a high contrast VFD display in an easy-to-read format. The 4302-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 4302-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 20µs, and pulse widths as narrow as 100µs, the 4302-QCW offers an effective and low-cost QCW solution. If you are looking for the non-QCW driver, see the 4302 LaserSource.
