125 Amp Laser Diode Driver for High Power Laser Bars, Stacks and Arrays
The LDI-344 series high power drivers for laser diodes offer up to 125 amps of bias current at a maximum voltage of 12V. They have integrated laser diode protection features such as current limit, soft start current ramp and power surge filters to make sure that your laser diodes are protected at all times. Additionally, these units offer CW, modulated, and Quasi-CW (QCW) slow pulsed modes and have an integrated function generator. Pulse width's as narrow as 29 microseconds are achievable.
The driver is packaged in a rack-mount 19 inch width chassis, and have a front panel keypad for fast, simple set-up.
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 LDI-334 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-334 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-334 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.
