Compact CH4 sensor based on difference frequency mixing of diode lasers in quasi-phasematched LiNbO3
{{output}}
A compact, portable and robust room temperature CH4 sensor is reported. By difference frequency mixing a 500 mW alpha-DFB diode laser at 1066 nm and an erbium-doped fiber amplified 1574 nm DFB diode laser in periodically poled lithium niobate up to 7 (mu)W of ... ...
