Noise characteristics of single-shot broadband CARS signals.
Spectrally resolved measurements of noise in resonant nitrogen coherent anti-Stokes Raman spectroscopy (CARS) are presented for three pump laser bandwidths. The experimental noise curves are compared with those calculated from a simple model involving statistically independent Stokes modes. The sources of noise in both resonant and nonresonant CARS spectra are discussed.
