A multi-quantum cascade laser system with field-proven performance, the MIRcatTM is an improved version of the first-generation MIRcat laser. It provides higher spectral repeatability, better heat management, longer wavelength options, and high-speed tuning. Because of its flexible, modular architecture, the MIRcat is truly a one-box, fully automated system.
This allows for the factory configuration of up to four pulsed or continuous wave/pulsed modules and the freedom to add or modify them afterward. The MIRcat has a tuning range of 1000 cm-1 (>6 µm) and wavelength coverage of up to >13 µm.
It also produces unmatched, industry-leading performance in critical areas such as peak tuning speeds exceeding 30,000 cm-1/s, output power up to 1 W, and TEM00 beam quality to enable high-efficiency fiber coupling. Wavelength repeatability can approach <0.1 cm-1 and CW RIN as low as -140 dBc/Hz thanks to new, higher-precision tuning mechanisms and lower-noise drive electronics.
