The OmniLux-AA-BB-CC-DD is an advanced wavelength tunable external grating cavity multiple quantum cascade laser system. Designed to accommodate up to four independent Quantum Cascade Lasers (QCLs), this system provides a broad wavelength coverage of approximately 3,000 nm. The QCLs, along with their thermoelectric coolers and collimating optics, are housed within a robust laser head that ensures trouble-free operation even in challenging environments. The OmniLux system is delivered as a complete package, including the laser head and a matched power supply, making it ready for immediate use upon installation at the customer's site. The overall wavelength coverage is determined by the specific center wavelengths, denoted as AA, BB, CC, and DD, chosen for the four QCLs.

Operating in a quasi-continuous wave (QCW) mode, the OmniLux system delivers 200-500 ns pulses with a repetition rate ranging from 500 kHz to 2 MHz, achieving a duty cycle of approximately 50%. This operational mode allows each QCL to produce an average power output exceeding 100 mW at the center of its tuning curve. The precision and reliability of the OmniLux system make it an ideal choice for applications requiring high power and tunable laser outputs.

The OmniLux laser head is engineered for precision and ease of use, operating efficiently at room temperature. It offers a wide range of available center wavelengths, 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 gain bandwidth of the QCLs, with the capability to house up to four lasers within the chassis. These lasers can be tuned either simultaneously or independently across their respective ranges, with a tuning speed of 100 ms for the entire range of each laser.

The OmniLux system features a 5V TTL gate output synchronized with laser tuning, ensuring precise control and integration with other systems. With an average power output stability of ±3% pulse-to-pulse and ±2% over hours, the system guarantees consistent performance. The laser system's collimated output beam has a divergence of less than 5 mrad, and its nearly diffraction-limited beam quality (TEM00) ensures high precision in applications. Additionally, the system is air-cooled and includes a guiding beam, a red 640 nm, 4 mW laser aligned with the IR beams to assist in alignment and operation.
