Unicorn-II™ Mid-IR Laser: High Power, Fixed Wavelength, Narrowband Output

The Unicorn-II series is a family of fixed-wavelength, narrowband mid-IR lasers with an average output power of up to 1 W. The Unicorn-II laser has an extremely robust and stable resonator structure providing users with superb linewidth control and wavelength stability, especially as environmental conditions vary. With a wide selection of quantum cascade laser chips available, Unicorn can be factory-configured to suit different application needs.

Unicorn systems include a SideKick™ laser controller, which gives you flexible, precise control of laser output power, temperature, and pulse parameters.

Features & Benefits:

  • Wavelength availability: 3-13 µm
  • CW* or pulsed output (up to 3 MHz/30% duty)*
  • Linewidths of < 1 cm-1 (pulsed, FWHM) or < 100 MHz (CW, tuned to SLM) Output power* to > 1 W (peak) or > 0.5 W (average)
  • Superior TEM00 beam quality and low beam pointing allows fiber coupling
  • Superb wavelength stability: ≤ 0.5 cm-1/hr within operating temperature range
  • High power stability: < 2% rms (1 hr)
  • Current (amplitude) modulation up to 1 MHz
  • SideKick™ controller, GUI, and SDK included with all systems
  • Proprietary HFQD™ circuitry protects your chips

*Requires suitable chip(s).
