The MonoLux Tunable Quantum Cascade Laser System is a sophisticated and versatile solution designed for precision and reliability. This system features a wavelength tunable external grating cavity quantum cascade laser (QCL), providing exceptional wavelength coverage of ±5% around the center wavelength, with broader tuning ranges available as an option. The laser head, which houses the QCL and collimating optics, is meticulously sealed to ensure trouble-free operation in various environments. The MonoLux system is delivered as a complete package, including the laser head and a laptop-based operating system, ready for immediate deployment at the customer's location.

Operating in a quasi-continuous wave (QCW) mode, the MonoLux system utilizes 200-500 ns pulses with a repetition rate ranging from approximately 500 kHz to 2 MHz, resulting in a duty cycle of around 50%. This operational mode allows the QCL to deliver an impressive average power output exceeding 500 mW at the center of its tuning curve, contingent on the selected center wavelength. For users requiring continuous wave (CW) operation, the MonoLux offers the option to select a 100% duty cycle. The system is ingeniously designed to be passively cooled, eliminating the need for fans and ensuring exceptionally quiet operation.

The MonoLux-AA variant of the Tunable Quantum Cascade Laser System offers enhanced tunability and flexibility. It supports both QCW and optional CW operations, with user-specified center wavelengths ranging from 3.8 µm to 10.2 µm. The system excels in wavelength accuracy and repeatability, providing better than 0.3 cm-1 accuracy and ±0.3 cm-1 repeatability. The output beam is collimated with a divergence of less than 5 mrad, maintaining nearly diffraction-limited beam quality. The system’s compact design, weighing less than 0.5 kg, and its compatibility with Windows XP or later computers via a USB interface, make it a convenient and powerful tool for various applications.
