| Abstract: | By theoretic analyzing the energy level structure of the color center and calculating the saturable optical intensity of the excited state absorption, the authors point out the possibility of realizing passive mode-locking by using LiF crystal with the relaxation time of the ground state in nanosecond magnitude. In colliding enhanced resonator Nd : YAG laser, mode-locked laser was realized by using LiF crystal. The single mode-locked pulse train with the average energy of 11. 8 mJ and the energy stability over 98% was obtained. |
