The MonoLux Tunable Quantum Cascade Laser System is an advanced, wavelength-tunable laser solution designed for precision and versatility. At the heart of this system is a wavelength-tunable external grating cavity quantum cascade laser (QCL), which offers wavelength coverage of ±5% around the center wavelength. This coverage can be expanded with optional broader tuning ranges to meet specific needs. The laser system is engineered for seamless integration, with its QCL and collimating optics securely housed within a sealed laser head, ensuring reliable performance even in challenging environments.

Designed for ease of use and optimal performance, the MonoLux system is delivered as a complete package, including the laser head and a laptop-based operating system. This setup allows for immediate operation upon installation at the customer's location. The QCL operates in a quasi-continuous wave (QCW) mode, providing 200-500 ns pulses with a repetition rate ranging from ~500 kHz to 2 MHz, resulting in a duty cycle of approximately 50%. This configuration enables the QCL to achieve an average power output exceeding 500 mW at the center of its tuning curve, depending on the selected center wavelength. For applications requiring continuous wave (CW) operation, the system offers an optional 100% duty cycle mode, all while maintaining quiet operation thanks to its passive cooling design.

The MonoLux-AA variant further enhances operational flexibility with its QCW operation at room temperature and optional CW mode. Users can specify their desired center wavelength from a selection of available options, including 3.8 µm, 4.1 µm, 4.5 µm, 4.8 µm, 6.3 µm, 6.8 µm, 7.3 µm, 8.5 µm, 9.5 µm, and 10.2 µm. The system's output spectrum is tunable over the QCL's gain bandwidth, with a tuning speed of 100 ms for the entire range. The MonoLux-AA supports continuous and repeated scans, step-and-scan functionality, and customizable scan speeds, providing precise control over the laser's output.

With its robust design, precise wavelength accuracy, and stable power output, the MonoLux system is an ideal choice for professionals seeking a reliable and versatile laser solution. Its compact size, lightweight design, and user-friendly computer interface further enhance its appeal, making it a valuable tool for a wide range of applications.
