Fig. 1. Experimental setup for an Nd:YAG dual-cavity master oscillator.
Fig. 2. (Color online) Output power (P1) of the TEM 00 LG 01
Fig. 3. (Color online) Temporal modulation of the output beam profiles due to the AOM on/off. The power was measured at the center and the edge of the beam at repetition rates of (a) 1 and (b) 100 Hz. The insets are the measured transverse intensity distribution by the CCD camera.
Fig. 4. Schematic diagram of the master oscillator and the three-stage Nd : YVO 4
Fig. 5. (Color online) Output power from the three-stage amplifier as a function of incident pump power. The signal input power was fixed to 0.5 W regardless of the beam profile.
Fig. 6. (Color online) (a) Output beam profiles, (b) theoretical and measured transverse intensity distributions for top-hat, TEM 00 LG 01
