Description

The MonoLux Tunable Quantum Cascade Laser System is an advanced laser solution designed for precise wavelength tuning and reliable performance in various environments. This system is centered around a single Quantum Cascade Laser (QCL), offering a 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 real-world conditions. The MonoLux system is delivered as a complete package, including the laser head and a laptop-based operating system, ready to be deployed at the customer's location.

Operating in a quasi-CW mode, the MonoLux emits 200-500 ns pulses at a repetition rate of approximately 500 kHz to 2 MHz, achieving a duty cycle of around 50%. This configuration allows the QCL to deliver an average power output exceeding 500 mW at the center of its tuning curve, contingent on the selected center wavelength. For applications requiring continuous wave (CW) operation, the system can be configured to a 100% duty cycle. The MonoLux's design includes passive cooling, eliminating the need for fans and ensuring quiet operation.

The MonoLux-AA variant further enhances the system's capabilities with user-specified center wavelengths ranging from 3.8 µm to 10.2 µm. The system's output spectrum is tunable over the gain bandwidth of the QCL, with a tuning speed of 100 ms for the entire range. Users can perform continuous and repeated scans, or step and scan to any wavelength within the tuning range via the laptop's operating program. The power output remains stable with ±3% pulse-to-pulse and ±2% average power stability over hours of operation. The system's output beam is collimated with a beam divergence of less than 5 mrad, ensuring nearly diffraction-limited beam quality.

With a compact design measuring 12 cm in width, 4.5 cm in height, and 13 cm in depth, and weighing less than 0.5 kg, the MonoLux system is highly portable. It interfaces with a computer via USB, requiring a Windows XP or later operating system with USB 2.0 support. Optional features include a guiding beam for optical alignment, enhancing the system's usability and precision in demanding applications.
