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.

Hedgehog™ Mid-IR Laser

Tune 100s of cm-1 at 1000 cm-1/s.

Cute name. Fearsome performance. Ideal for laboratory or OEM use, the Hedgehog Mid-IR Laser is DRS Daylight’s next-generation tunable laser head. Built on our proven External Cavity Quantum Cascade Laser technology, the Hedgehog laser is a unique combination of small size, tuning speeds to > 5000 cm-1/s, CW or pulsed output, high power, TEM00 beam quality, and unmatched spectral repeatability.

Molecular spectroscopy applications benefit from rapid, high-SNR data acquisition. Probing multiple molecules, or probing an absorption feature with high dynamic range, also benefits from broad mid-IR tuning. The Hedgehog system provides these benefits, with its wide, rapid tuning across the mid-IR spectrum, low-noise output, and high spectral and spatial beam quality. Its sealed, alignment-free design and GUI and SDK included as standard let you access this performance with ease.

Select from three standard Hedgehog models: Hedgehog (tunes up to 200 cm-1), Hedgehog-UT (tunes up to 400 cm-1), and Hedgehog-LT (tunes up to 30 cm-1).
