Where to Buy Quantum Cascade Lasers

RPMC Lasers offers the QCL series of high-power, high-performance pulsed quantum cascade lasers, based on proprietary technology, which incorporates high-powered diodes (typically watt-level) emitting in the main transmission bands of the atmosphere (4.0 µm, 4.6 µm, 4.8 µm, 9.x µm), as well as newly developed wavelengths up to 17 µm. The ITAR free QCLs we offer exhibit outstanding performance in terms of power and wall-plug efficiency.

Alpes Lasers designs and manufactures a wide range of QCLs with wavelengths from 4 to 14 μm and powers up to hundreds of milliwatts. This includes FP, DFB, THz, frequency comb and external cavity lasers in the mid-IR. Additionally, Alpes offers uniquely fast and widely tuneable lasers with our ET and XT product line.

DRS Daylight Solutions offers a wide range of quantum cascade lasers:

• The MIRcat-QT™ is a very rapidly wavelength-tunable version with up to 30,000 cm⁻¹/s, covering wavelengths beyond 13 μm.
• The Hedgehog™ models are wavelength-tunable laser for mid-IR spectroscopy with up to 0.5 W average power and 1 W peak power. Ultra-quiet, superior wavelength repeatability.
• The CW-MHF™ is the ultimate tool for high-resolution, mid-IR spectroscopy with high spectral resolution and phase-continuous tuning to avoid jumping over spectral lines.
• The Aries-2 series is a family of fixed-wavelength, narrowband mid-IR lasers with an average output power of up to 1 W.
• The H-Model mid-IR laser offers high-power, mid-IR OEM laser performance in a compact footprint. CW and pulsed operation are possible.
• We also have high-power multi-color laser systems (VIS, NIR, SWIR, MWIR, and LWIR) with best-in-class performance for aircraft protection.

Frankfurt Laser Company offers quantum cascade laser diodes with emission wavelengths from 4 μm to 13 μm with either DFB or Fabry–Pérot type.

Sacher Lasertechnik offers quantum cascade lasers with emission between 4 μm and 12 μm, suitable for applications like molecular spectroscopy.
