Product Overview:

High Power 75 Amp Laser Diode Bar & Array Controller Overview

The LDC-175 high power controller is designed for power laser diode bars and arrays which require high current, and provide industry-leading safety features to protect your high-power laser diode devices.

Protection Features for High Power Laser Diodes

The LDC-175 driver includes laser diode protection features such as current limit and soft start current ramp to make sure that your laser diodes are protected at all times. The soft-start current ramp is pre-set at the factory to 300 milliseconds, but is user-adjustable. This current ramp-up and ramp-down function is designed to protect the laser from thermal shock during power-up and power-down sequences.

The LDC-175 also includes a brown-out and black-out power surge clamp, AC line filters, and a fast response to shunt the current in the event of an open circuit. There is an interlock safety connection as well as a front panel Emergency-Stop kill switch to ensure the laser is operated only when the user has determined it is safe to do so.

Laser Driver Features

The current output can be set to a (CW) continuous wave mode or can be set to run in a quasi-CW mode. The QCW mode can be triggered externally or internally using an on-board pulse generator. The driver delivers clean pulses with pulse widths from 30 μsec to CW.

TEC Controller for Precise Temperature Control of Laser Bars

The TEC controller is a bipolar +/- 7 amp and 48 volt controller designed to work with Peltier coolers mounted under or inside the bar or array device. The full PID control loop settles the temperature quickly and keeps the temperature at the desired set-point. Although they ship with factory set default PID variables, the user can adjust each variable to optimize the settling time of the temperature control loop.

Affordable High Power Controller for Laboratory R&D or Laser System Integration

These units are an ideal choice for a small form factor, high power laser control module for use in the lab for R&D or for use in a laser system product.

Laser Driver Control User Interface

The LDC-175 front-panel controls provide fast and simple setup, and an RS232 interface with LabView drivers is included standard. The LabView GUI makes set-up and control of the system fast and simple. An optional USB digital interface is available; inquire for details on ordering the USB control option.
