Product Overview:

LDC-506 High Power Laser Diode Driver Overview

The LDC-506 laser diode driver features high compliance voltage to reliably drive multi-single emitter lasers from companies like nLight, Lumentum and II-IV. The LDC-506 can also drives multi-emitter devices designed for series operation.

Modulation, Internal Function Generator, and QCW Pulse Modes

The LDC-506 laser diode controller offers CW laser current output, flexible modulation capabilities, and a QCW mode. The rear panel of the controller has a BNC input (10kΩ input impedance) for an analog or TTL digital modulation up to 50 kHz. These controllers have an internal function generator which can be used to drive quasi-CW pulses in continuous, single, and burst-mode. In QCW mode, the user can also set 25μs-to-CW pulses to trigger from an external TTL signal source.

Laser Diode Protection Features

The LDC-Series instruments offer a high level of laser diode protection to ensure that your device is protected at all times. Soft-start current, current and temperature limits, and a fast shut-down sequence keep your device protected at all times. Transient filters and AC line filters protect the laser against brown-out or black-out power conditions. A back-panel safety interlock connector ensures that the laser diode current is not switched on until the user has determined it is safe to do so, and a front panel Emergency Stop button provides an additional layer of safety for the user. 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.
