Model CW-MHF -Mid-IR Laser Laser System
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, theCW–MHFlaser achieves this performance with a highly stable laser cavity that, guided by finite element analysis, was designed to reduce susceptibility to acoustic perturbation. TheCW–MHFlaser also includes two ways to modulate wavelength: via a PZT or current modulation. This exclusive combination of wideMHFtuning, narrow-linewidth operation, and modulation capability enables high-resolution spectroscopy and/or locking to a wavelength reference.
