Long-Wavelength Infrared Lasers: QCL Laser Diodes

Learn More About LWIR Lasers

CO2 lasers and Quantum Cascade Lasers (QCL) are the most common lasers in this wavelength spectrum.  Our QCL lasers are available with both single-mode and multi-mode beam profiles, and typically have a free-space output. QCLs in the LWIR wavelengths are ideal for many applications in Industrial markets and are widely used in many various Gas Sensing applications.  Long-Wavelength Infrared lasers emit in the main transmission bands of the atmosphere, between 9.0 µm and 17 µm and are available in the HHL Package, OEM package including the driver, and a turn-key solution.

LWIR Laser Products

We offer Quantum Cascade Lasers (QCLs) with LWIR output. Our LWIR products are available with up to 300 mW average power, single-mode and multimode beam profiles, free-space output, narrow linewidth options, and various packaging and integration levels from component to OEM to turnkey systems.

Some LWIR Applications

Some popular LWIR applications include many various Gas Sensing applications.
