Experimental investigation about influences of longitudinal-mode structure of pumping source on a Ti:sapphire laser

Using a multi-longitudinal-mode (MLM) and a single-longitudinal-mode (SLM) all-solid-state green lasers to be the pumping sources of a continuous-wave Ti:sapphire laser, respectively, the intensity-noise dependence of the Ti:sapphire laser on the longitudinal-mode structure of pumping sources is experimentally studied. The comparison between the theoretical prediction based on the quantum-mechanical model and the experimental measurement for the intensity-noise spectra is presented.
