The field-proven multi-quantum cascade laser system of the first generation of MIRcat laser is enhanced by the MIRcat™ with longer wavelength possibilities, more spectral repeatability, better thermal management, and high-speed tuning.
With its versatile, modular architecture enabling factory configuration of up to four pulsed or continuous wave/pulsed modules and the flexibility to add or upgrade modules later, the MIRcat is a one-box, fully automated system. It provides wavelength coverage up to >13 µm and a tuning range reaching 1000 cm-1 (>6 µm).
It achieves unparalleled, industry-leading performance in crucial aspects such as peak tuning speeds surpassing 30,000 cm⁻¹/s, output power capabilities up to 1 W, and TEM00 beam quality for facilitating high-efficiency fiber coupling.
With a novel, higher-precision tuning mechanism and lower-noise drive electronics, CW RIN can be as low as -140 dBc/Hz, and wavelength repeatability can be as precise as < 0.1 cm⁻¹.
