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).

Features & Benefits:

  • Wavelength availability: 3-13 µm
  • Tune up to 400 cm-1 at speeds up to 5000 cm-1/s
  • CW* or pulsed output (up to 3 MHz/30% duty)*
  • Ultra-quiet CW: RIN as low as -140 dBc/Hz enables higher-SNR spectroscopy
  • Superior wavelength repeatability for higher-accuracy spectroscopy
  • Superb TEM00 beam quality and low beam pointing allows fiber coupling
  • High output power for high SNR* of > 1 W (peak) and > 0.5 W (average)
  • SideKick™ controller, GUI, and SDK standard with all systems
  • Proprietary HFQD™ circuitry protects your chips

*Requires suitable chip(s).
