Product Overview:

70 Amp Laser Diode Driver for High Power Bars and Arrays

The LDI-607 series high power drivers for laser diodes offer up to 70 amps of bias current at a maximum voltage of 5V. The integrated function generator can be programmed to generate QCW pulses from 29 microseconds to CW. The QCW pulse mode feature is capable of delivering continuous pulses, single pulses, and pulse bursts which are internally or externally triggered.

Customized Protection for High Power Laser Bars and Arrays

These current sources feature multiple levels of built-in laser diode protection which have been optimized for high power bars and arrays. One of the unique features is a user programmable soft-start ramp of the bias current to the device under test. The factory sets the ramp time to 300 milliseconds as a default, but the user can adjust this time period from 1 millisecond up to 10's of seconds. This current ramp up and down function is designed to protect the laser from thermal shock during power up and down sequences.

The LDC-607 also offers features such as current limit, 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 Control User Interface

The LDC-607 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.

Controller Power Interface

The LDC-607 utilizes high current DSUB-5W5 style connector on the rear panel. A 15-pin D-sub connector is included for ancillary control functions, including external photodiode measurement, Laser-On Indicator LED, temperature sensor input, and an external cooling fan control.
