Abstract

A technique of lidar for atmospheric gas detection by using stimulated Raman gain spectroscopy (SRGS) without any tunable laser was presented. The lidar equation for CO2, CH4 and H2 in the atmosphere was used for estimation of detectable range and detection sensitivity. The signal in case of SRGS was obtained by a coherent light beam. The study showed that the detection sensitivity can be increased by using long optical passes without any limitation caused by the phase-matching condition.
