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.
