Abstract
We experimentally demonstrate a diode-pumped passively Q-switched Yb:Lu3Al5O12 ceramic laser operating at 1031 nm or 1047 nm based on a semiconductor saturable absorber mirror (SESAM) and an output coupler (OC) of different transmission (T). For an OC of T=7.5% and an absorbed power of 9.25 W, the laser operates at 1031 nm with a maximum average output power of 1.47 W, the corresponding optical-to-optical efficiency of 15.85%, and the slope efficiency of 19.04%, respectively. The pulse width and the pulse repetition frequency (PRF) are about 1.23 μs and 245.04 kHz, respectively. For an OC of T=1.6% and an absorbed power of 9.25 W, the laser operates at 1047 nm with a maximum average output power of 0.85 W, the corresponding optical-to-optical efficiency of 9.21%, and the slope efficiency of 8.43%, respectively. The pulse width and the PRF are 1.49 μs and 112.63 kHz, respectively.
