Product Overview:

High Power CW/QCW Laser Diode Driver Overview

This high power CW / QCW laser diode driver is designed to power the diode arrays for pumping high-power solid-state or fiber lasers. It is optimized for use as part of laboratory, educational, experimental, and industrial applications. It has current limit, duty cycle limit, and safety interlocks to help protect the laser diodes and the user.

The operating parameters are adjusted and controlled via front panel, with an LCD display. The controller comes standard with an RS232 interface for connection to a control computer, and RS485 is available optionally.

Options to Increase Functionality and Versatility

This high power CW/QCW laser diode driver can be assembled into the Multichannel Electrical Power Supply System (MEPSS), allowing up to 20 drivers to be controlled by a single operating computer. The MEPSS is meant for applications such as research into laser-matter interaction, inertial confinement fusion, laser diode array testing, and other cases where multiple high power lasers are controlled simultaneously.

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

Additionally, the flexible internal architecture of the driver means it can be modified according to customer requirements for a specific load.
