Abstract
The effect of finite-bandwidth multimode pump lasers in CARS is normally accounted for by an intensity convolution integral based on gaussian (thermal) pump sources. This paper presents a derivation of the convolution integral for non-gaussian pump sources derived from frequency doubling. The modified convolution integral makes it possible to identify regions of insensitivity to pump stochastic properties.
