Over temperature input shuts off current source output GPIB/IEEE-488 interface and trigger output Newport’s ILX Lightwave LDX-3232 High Compliance Laser Diode Driver is the industry’s only laser diode driver specifically developed for controlling high compliance voltage devices such as quantum cascade laser diodes. Careful attention to design allows these drivers to deliver up to 4 A of low noise current at up to 15 V with a stability of better than 20 ppm. This performance is critical for development of room temperature quantum cascade lasers and spectroscopic applications using quantum cascade lasers. The LDX-3232 includes multiple levels of laser protection to safe guard expensive quantum cascade lasers during operation. Protection features include: slow start circuit, floating output, AC transient suppression, independent current limits, and intermittent contact protection.

In addition to precision current control, the LDX-3232 is loaded with standard features such as dual current ranges, constant power control, fine/coarse setpoint control, laser current and voltage measurement, photodiode current display modes, forward voltage adjustment and measurement, and an external modulation input.
Quantum Cascade Laser Mount
Suitable in vacuum or nitrogen purged environment.
Newport’s ILX Lightwave LDM-4872 Quantum Cascade Laser Mount provides convenient mounting for quantum cascade laser diodes in a vacuum or nitrogen purged environment. The 4872 is offered with standard mounting plates for C-Mount (C-Block), Alpes COC, and customer proprietary QCL packages. A wide temperature control range is accomplished by an integrated thermoelectric module and a high performance water-cooled cold plate which provides for an active control range of -30 °C to 30 °C with heat loads up to 10 W. Fixture design and precision machining result in low, repeatable thermal resistance between the QCL and Key Features Supports C-Block, COC, and customer proprietary QCL packages Active temperature control from -30 °C to 30 °C Compatible with the LDX-3232 CW QCL Driver Ports for vacuum evacuation or nitrogen purge Optional XYZ stage with multiple ZnSe lens options

LDM-4872 minimizing the temperature difference between the laser and the fixture. The LDM-4872 mount is compatible with ILX Lightwave current sources and temperature controllers through interconnect cabling for quick setup. Optical table mounting is made possible through ANSI and metric spaced mounting holes on the base of the mount
