We present a simple method and its experimental implementation to determine the pulse durations and linear chirps of the pump-and-probe pulse and the Stokes pulse in a coherent anti-Stokes Raman scattering microscope at sample level without additional autocorrelators. Our approach exploits the delay line. ubiquitous in such microscopes. to perform a convolution of the pump-and-probe a... https://www.itsmajorlook.com/
