摘要: We demonstrate experimentally that coherent anti-Stokes Raman microspectroscopy with high spectral resolution is achieved using femtosecond laser pulses chirped up to a few picoseconds by glass elements of known group-velocity dispersion without significant intensity losses. By simply choosing the length glass, chirp Stokes and pump tailored obtain given Fourier limit pulse duration. show for durations shorter than or comparable coherence time, maximum signal occurs arriving after pulse, time-ordering effect confirmed numerical simulations.
