We investigate output characteristics of a Q-switched laser composed of twoYb:YAG disk laser modules. To generate a Q-switching pulse, a semiconductor saturableabsorption mirror (SESAM) is installed in the laser resonator. The Q-switched outputcharacteristics depends on the laser mode sizes on an Yb:YAG material and a SESAM. Thelaser mode sizes are controlled by the focal length of a lens which is used for a lasermode beam to be focused on a SESAM. Hence we investigate the dependence of theQ-switched output characteristics on the focal lengths of the several focusing lenses. Theexperimental results and the numerical analysis show that the Q-switching pulse could bewell generated by the focusing lens with the longest focal length among the used lenses.
Abstract
We investigate output characteristics of a Q-switched laser composed of twoYb:YAG disk laser modules. To generate a Q-switching pulse, a semiconductor saturableabsorption mirror (SESAM) is installed in the laser resonator. The Q-switched outputcharacteristics depends on the laser mode sizes on an Yb:YAG material and a SESAM. Thelaser mode sizes are controlled by the focal length of a lens which is used for a lasermode beam to be focused on a SESAM. Hence we investigate the dependence of theQ-switched output characteristics on the focal lengths of the several focusing lenses. Theexperimental results and the numerical analysis show that the Q-switching pulse could bewell generated by the focusing lens with the longest focal length among the used lenses.
