CW-MHF™ Mid-IR Laser

Tune > 30 cm-1 Without Mode Hops

The CW-MHF Mid-IR Laser is the ultimate tool for high-resolution, mid-IR spectroscopy. If you need high spectral resolution, phase-continuous tuning to avoid jumping over spectral lines, or both, the DRS Daylight CW-Mode-Hop-Free laser will meet your needs. Narrow-linewidth operation and MHF tuning is a high bar to reach in any laser system. Unique in the industry, the CW-MHF system provides open-loop linewidths of ≤ 5 MHz (over 100 ms) and MHF tuning to > 30 cm-1, and often to > 100 cm-1*. Drawing on years of precision engineering and manufacturing experience, the CW-MHF laser achieves this performance with a highly stable laser cavity that, guided by finite element analysis, was designed to reduce susceptibility to acoustic perturbation. The CW-MHF laser also includes two ways to modulate wavelength: via a PZT or current modulation. This exclusive combination of wide MHF tuning, narrow-linewidth operation, and modulation capability enables high-resolution spectroscopy and/or locking to a wavelength reference.

MIRcat Mid-IR Laser

Peak velocities up to 30,000 cm-1/s

The MIRcat adds high-speed tuning, higher spectral repeatability, improved thermal management, and longer-wavelength options to the first generation of the MIRcat laser, a field-proven multi-quantum cascade laser system. The MIRcat is truly a one-box, fully automated system with a flexible, modular design that allows factory configuration of up to four pulsed or continuous wave/pulsed modules, plus the option to add or upgrade modules later. The MIRcat offers a tuning range approaching 1000 cm-1 (> 6 µm) and wavelength coverage to > 13 µm. It also delivers unmatched, industry-leading performance in critical areas like peak tuning speeds of > 30,000 cm-1/s, output power up to 1 W, and TEM00 beam quality to enable high-efficiency fiber coupling. A new, higher-precision tuning mechanism and lower-noise drive electronics provide wavelength repeatability as high as < 0.1 cm-1 and CW RIN as low as -140 dBc/Hz.
