ILX Lightwave offers a range of laser diode drivers, temperature controllers, thermoelectric chillers, and mounting fixtures for precision control of quantum cascade lasers for research and development or manufacturing test. The LDX-3232 Quantum Cascade Laser Diode Driver offers high stability, low noise CW and high compliance voltage up to 15V. Benchtop temperature controllers with high stability and accuracy provide precise temperature control of quantum cascade lasers during testing or qualification. Laser diode thermoelectric chillers are designed specifically for laser control by providing high temperature stability and protection of lasers from common chiller faults. For a complete quantum cascade laser testing solution, ILX offers a mount with XYZ stage, mid-IR lens, and the ability to operate the QCL in a vacuum environment.
