摘    要:本文从理论上指出,在分子振动能级的横向弛豫时间远小于激光相干时间的条件下,相干反斯托克斯喇曼散射(CARS)信号能够反映出激光光场的相干特性,据此可直接了解其相干时间并推算出激光的线宽。实验记录了苯、甲苯的CARS光信号与激光延时时间的关系,得出了激光的相干时间和线宽。

关 键 词:CARS  相关函数  相干性  激光

Abstract:In this peper, we propose theoretically that, if the transvers relaxation time of molecule's vibration is much shorter than the correlation time of pumping light, the correlation time and frequency width of the light can be estimated by CARS technique.The experiments of CARS of benzene and methylbenzene were Performed and the correlation time and frequency width of laser were estimated.
Keywords:ARS  Gaussian random variable  correlation function
