Experimental Researches of Active-Passive Colliding Pwse Mode Locking

A series of experiments for active-passive colliding pulse mode locking in YAG laser is described in this paper. We have obtained experimental results of output energy, pulse width and energy stability of mode locking as functions of pumping energy,dye concentration, modulation depth, match of cavity length and position of dye cell. And the optimum operating of YAG active-passive colliding pulse mode locking laser has been obtained as well.
