Description
The MonoLux Tunable Quantum Cascade Laser System is a cutting-edge solution designed for precision and versatility in various scientific and industrial applications. This system features an advanced wavelength tunable external grating cavity quantum cascade laser, which includes a single QCL. With a wavelength coverage of ±5% around the center wavelength, the MonoLux offers a broader tuning range as an optional feature, making it adaptable to specific user needs. The laser head, which houses the QCL and collimating optics, is meticulously sealed to ensure reliable performance even in challenging environments. The complete system is delivered ready to use, with a laptop-based operating system that can be easily deployed at the customer's location.
Operating in a quasi-CW mode, the MonoLux delivers 200-500 ns pulses at a repetition rate of approximately 500 kHz to 2 MHz, achieving a duty cycle of around 50%. This operation mode allows the QCL to produce an average power output exceeding 500 mW at the center of its tuning curve, contingent on the chosen center wavelength. For applications requiring continuous wave performance, the system can be configured for CW operation with a 100% duty cycle. The passive cooling design eliminates the need for fans, resulting in ultra-quiet operation.
The MonoLux-AA variant offers additional flexibility with its QCW operation at room temperature, featuring pulse durations ranging from 50 ns to 500 ns and a pulse repetition rate between 1 MHz and 2 MHz. Users can specify their desired center wavelength from a selection that includes 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 is capable of continuous and repeated scans over the entire tuning range, or step and scan to any wavelength within the range, with tuning speeds of 100 ms for the complete range. Power stability is maintained within ±3% pulse-to-pulse and ±2% average power over extended periods, ensuring consistent performance.
With a compact design, the MonoLux system measures 12 cm in width, 4.5 cm in height, and 13 cm in depth, weighing less than 0.5 kg. The output beam is collimated with a divergence of less than 5 mrad and offers nearly diffraction-limited quality. The system interfaces via USB, requiring a Windows XP or later computer with USB 2.0. This makes the MonoLux an ideal choice for researchers and professionals seeking a reliable, high-performance laser system that is both versatile and user-friendly.
