Abstract

An analysis of broadband dye laser spectral noise is presented. Particular reference is given to the effect of such noise on broadband single-pulse CARS spectra. A simple theory which accurately predicts both dye laser and CARS spectral noise is presented. Methods for reducing CARS spectral noise are identified and discussed. A laser geometry based on a corner cube resonator is examined which significantly reduces dye laser noise.
