Laser Diode Instrumentation Guide

Newport and ILX Lightwave Offer the Widest Range of High Quality Precision Laser Diode Control Instrumentation Available

Laser Diode Instrumentation is used to precisely control a laser diodes optical output, while protecting the laser diode from thermal or electrical damage while operating. We offer a wide variety of Laser Diode Mounts and fixtures for mounting your diode that are compatible with our laser diode drivers and controllers. We also offer accessories and cables with standard compatibility with our instruments and mounts.

Types of Laser Diode Instruments

Laser Diode Instruments can be broken into five categories. Laser Diode Drivers are used to control the current supplied to a laser diode. Laser Diode Temperature Controllers are used to control a thermoelectric cooler (TEC), that is either imbedded in the laser diode package or is integrated into the laser diode mount. Laser Diode Controllers include both a laser diode driver and a laser diode temperature controller in a single device. Pulsed Laser Diode Drivers are used to modulate a laser diode by pulsing it's driver current. Modular Laser Diode Controllers are multi-channel instruments that can be configured with a laser diode driver, temperature control modules, or combo laser diode driver and temperature controller modules. Newport also offers a variety of Laser Diode Control Kits which contain all the necessary current and temperature controllers as well as cables and mounting accessories needed in one convenient package. For volume testing of laser diodes we offer Laser Diode Burn-in Racks.  For high power laser diode, bars, and stacks we offer High Power Laser Diode Instrumentation.
