In this research, an array-pumped, microchip and ultra-short-cavity continuous-wave 1064 nm Nd:YVO4 laser was explored. The laser emitted single-longitudinal-mode (SLM) and 2 × 2 arrayed output with Dammann array pumping, and the total power of 2 × 2 arrayed output reached 558.0 mW with a 0.75-pm linewidth at 1.86-W pump power. A comparison of array pumping with single-point pumping for SLM operation was conducted, and it showed the advantages of array pumping microchip laser for high-power, high-beam-quality, and stable SLM operation. The proposed laser could be useful as a seed source for an array master-oscillator power amplifier system and for high-precision parallel laser ranging and guidance. The proposed method could be extendable for high-power SLM array laser by adopting higher-order array pumping.
