Fig. 1. Experimental setup for the compact AO Q-switched Yb:YCOB laser. M1 is an input mirror coated on the front face of the Yb:YCOB crystal. M2 is an output coupler. Inset: Yb:YCOB crystal.
Fig. 2. Laser spectrum for the CW laser operation and pulse laser operation at 1 kHz, 0.5 kHz, 0.2 kHz, and 0.1 kHz.
Fig. 3. Laser output powers under different PRFs. The dotted lines represent the linear fitting, and η represents the slope efficiency.
Fig. 4. Relationship between the pulse duration and the incident pump power at pulse repetition rates of 1 kHz, 0.5 kHz, 0.2 kHz, and 0.1 kHz.
Fig. 5. Laser pulse trains measured at the PRF of (a) 1 kHz and (c) 0.1 kHz. (b), (d) illustrate the corresponding individual pulse profile.
