Abstract :
Summary form only given. Compact, room-temperature mid-infrared laser sources have a variety of applications in gas detection. We have developed a room-temperature mid-IR laser source based on the frequency mixing of two diode lasers in periodically poled lithium niobate waveguides. Output powers greater than 1 /spl mu/W have been obtained. This laser source has been used to measure strong absorption lines of water vapor at 2.7 /spl mu/m.
