Quintessence Photonics awarded contract for diode lasers used in optical sensing applications

July 28, 2006, Sylmar, CA--Quintessence Photonics Corporation, a subsidiary of QPC Lasers, Inc., designer and manufacturer of high-brightness, high-power semiconductor lasers, has won a contract to develop and deliver high-precision direct-diode optical sensing lasers based on its recently released high-power semiconductor lasers with internal gratings.

Optical sensing is critically important in the defense, homeland security, and industrial markets where the measurement of distance, temperature, and/or pressure is required for a broad range of applications such as range finding on the battlefield, opto-acoustic sensors in submarine towed arrays, monitoring and security of oil/gas pipelines and power lines, and high precision thickness/position monitoring in the semiconductor and pharmaceuticals industry.

To be suitable for high-precision metrology, lasers must emit light with an extremely narrow and accurate wavelength spectrum. For high power applications, this is typically achieved using multi-stage gas, solid-state, or fiber lasers. QPC's Internal Grating technology addresses this market by providing a more lightweight, compact and cost effective micro-chip laser solution.
