Lancaster, D.Tittel, F.Richter, D.Petrov, K.Curl, R.2010-08-192010-08-191998Conference on Lasers and Electro-Optics - Technical Digest, 1998: pp.91-921557525390http://hdl.handle.net/2440/59905This work describes the design and performance characteristics of room-temperature mid-infrared diode-pumped sensors capable of either single or multicomponent real-time trace gas detection in ambient air. The difference-frequency-generation based sensor technology employs periodically poled lithium niobate crystals with multiple grating periods pumped by two single-frequency solid-state lasers and a thermoelectrically cooled HgCdTe infrared detector.enCopyright status unknownConference paper003000113810.1109/CLEO.1998.67590965144
