Product Overview:

LDC-157 High Power Laser Diode Driver Overview

The LDC-157 laser diode driver is designed with high compliance voltage to precisely and safely bias multi-single emitter lasers from companies such as nLight, Lumentum and II-IV. Rhe LDC-157 can also be used to drive multi-emitter devices wired for series operation.

Modulation, Internal Function Generator, and QCW Pulse Modes

In addition to CW (continuous wave) mode of operation, the LDC-157 laser diode controller offers flexible modulation capabilities and a QCW mode. The rear panel of the controller has a BNC input for an analog or TTL digital modulation, DC up to 50 kHz, input with a 10k Ω input impedance.

The controller has 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 a remote TTL signal source.

Laser Diode Protection Features

These units offer the highest level laser diode protection available to ensure that your device under test 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. Additionally, 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.

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.
