The MonoLux Tunable Quantum Cascade Laser System represents a pinnacle of precision and adaptability in laser technology. This sophisticated system is engineered to deliver exceptional wavelength tunability, allowing for coverage of ±5% around a designated center wavelength, with broader tuning ranges available upon request. The heart of the MonoLux system is its laser head, which houses the quantum cascade laser (QCL) and collimating optics, all sealed to ensure reliable performance in various environments. Designed as a complete package, the MonoLux includes the laser head and a laptop-based operating system, facilitating immediate deployment and operation at the customer's location.

Operating predominantly in a quasi-continuous wave (QCW) mode, the MonoLux achieves pulse durations between 200-500 ns with repetition rates ranging from approximately 500 kHz to 2 MHz, resulting in a duty cycle of around 50%. This mode enables the QCL to deliver an average power output exceeding 500 mW at the center of its tuning curve, contingent upon the selected center wavelength. For applications requiring continuous wave (CW) operation, the system can be configured to operate at a 100% duty cycle. The passive cooling design of the MonoLux ensures quiet operation, free from the noise typically associated with fan-cooled systems.

The MonoLux-AA model further enhances the system's versatility with its tunable quantum cascade laser features. It offers user-specified center wavelengths, including options like 3.8 µm, 4.1 µm, 4.5 µm, and several others, up to 10.2 µm. The system supports rapid tuning across the gain bandwidth of the QCL, with a tuning speed of just 100 ms for the entire range. Users can perform continuous and repeated scans, or opt for step-and-scan functionality to achieve precise wavelength targeting. The system's power output remains stable, with an average power of 500 mW at the center of each QCL tuning curve, and it maintains pulse-to-pulse stability within ±3%.

In terms of physical specifications, the MonoLux is compact and lightweight, measuring 12 cm in width, 4.5 cm in height, and 13 cm in depth, with a weight of less than 0.5 kg. It interfaces with computers via USB, requiring a Windows XP or later operating system with USB 2.0 compatibility. Additionally, an optional guiding beam feature, utilizing a red 640 nm, 4 mW laser, aids in optical arrangements by aligning with the IR beams. The MonoLux system exemplifies cutting-edge laser technology, providing unmatched precision, adaptability, and ease of use for a wide range of applications.
