Abstract

The cw and femtosecond laser operations of Yb 3 + : CaYAlO 4 (Yb:CYA) are demonstrated. The laser emitted a maximum cw power of 1.94 W with a slope efficiency ( η slope ) of 71% and an optical-to-optical efficiency ( η opt ) of 51%. Under mode-locking operation, the laser emitted near transform-limited pulses with 156 fs pulse width, 8.1 nJ pulse energy and 0.74 W average power. The η slope and η opt of the mode-locked laser were 37% and 20%, respectively.
