【Abstract】 Light intensity versus the rotation angle of the corner cube prism in cavity is analyzed theoretically and simulated numerically. Experimental results show that by using polarized mirror as output mirror, the ratio of mode-locking and depth of line polarized light approach 100% , and by rotating the corner cube prism to change the coupling output and to control the inner light intension, passive mode-locking laser or passive Q-switched laser was obtained respectively. Pulsed laser energy is up to 166. 5 mJ, and the ratio of dynamic to static was as high as 59. 7%.更多还原
