Product Overview:

High Current CW/QCW Laser Diode Driver Overview

This high power CW / QCW laser diode driver is designed to drive high current laser stacks and arrays. Designed and optimized for use as part of laboratory, educational, experimental, and industrial applications, the driver has current limit, duty cycle limit, and safety interlocks to help protect the laser diodes and the user.

The rack-mounted controller includes an RS232 interface and PC-based software for control. The front-panel provides easy control of the driver, with a large LCD display and adjustment knob .

Versatile Options Increase Driver Functionality

Multiple high power CW/QCW laser diode drivers can be used to build the Multichannel Electrical Power Supply System (MEPSS). The MEPSS can operate up to 20 laser diode drivers, and is designed for things like inertial confinement fusion, laser-matter interactions, laser diode array testing, and other cases where multiple high power lasers are controlled simultaneously.

The laser diode driver can be factory-equipped with a high power temperature controller for laser temperature stabilization; inquire for details and options.

Additionally, the flexible internal architecture allows for factory customization to suit customer requirements for a specific load. Optionally, the driver can be equipped to operate in a temperature range of –40°C / +50°C.
