摘要：
The development and characterization of a compact mid-infrared source for high-resolution spectroscopic detection of trace gases such as methane and water vapor at 3.3 mu m in ambient air is reported. This source utilizes difference frequency generation (DFG) in a periodically poled LiNbO3 (PPLN) crystal pumped by two single-frequency diode lasers. A maximum DFG power of 1.6 mu W at 3.6 mu m was generated with a pump power of 61.4 mW at 832 nm and a signal power of 41.5 mW at 1083 nm incident on a 19-mm-long PPLN crystal, which corresponds to a conversion efficiency of 335 mu WW-2 cm(-1).
