- Quintessence Photonics Wins Government Contract for Mid-Infrared Lasers
Quintessence Photonics Corp. announced today it has won a contract from the US government to develop high-power mid-infrared lasers. The Phase III award is a follow-on to a previous contract funded by the US Army to deliver semiconductor lasers that emit light in the mid-infrared wavelength; the amount of the contract was not disclosed. Low-cost, high-power mid-infrared lasers have a variety of defense and homeland security applications, including protection of aircraft, ships and armored vehicles from heat-seeking missiles and standoff detection of chemical weapons. Free-space optical communications and imaging on the battlefield benefit from mid-infrared sources since, unlike visible and near-infrared wavelengths, communications at mid-infrared wavelengths are relatively immune to fog, smoke and solar background impairments, the company said. Quintessence Photonics, a subsidiary of QPC Lasers Inc., is a manufacturer of high-brightness, high-power semiconductor lasers and is based in Sylmar, Calif.
- Electromagnetic radiation detectable by the eye, ranging in wavelength from about 400 to 750 nm. In photonic applications light can be considered to cover the nonvisible portion of the spectrum which includes the ultraviolet and the infrared.
