Abstract

The possibilities of using a hyperbroadband nonlinear-optical frequency converter of femtosecond pulse radiation for design of multicomponent mixture analyzers are investigated. Key elements of frequency converters are new bi-axis nonlinear crystals where the conditions of phase and growth velocity matching are fulfilled simultaneously. The method of broadband lidar sensing of atmospheric gases by the DOAS-technique (Differential Optical Absorption Spectroscopy) is described. The numerical simulation of DOAS sensing of atmospheric gas components using the frequency-converted femtosecond radiation is carried out.
