摘要

这项研究探索了一种阵列泵浦、微芯片和超短腔连续波 1064 nm Nd:YVO4 激光器。该激光器在 Dammann 阵列泵浦下发出单纵模（SLM）和 2 × 2 阵列输出，在 1.86 W 泵浦功率下，2 × 2 阵列输出的总功率达到 558.0 mW，线宽为 0.75 pm。比较了阵列泵浦和单点泵浦在 SLM 工作中的应用，结果表明阵列泵浦微芯片激光器在高功率、高光束质量和稳定的 SLM 工作中具有优势。所提出的激光器可用作阵列主振荡器功率放大器系统的种子源，也可用于高精度并行激光测距和制导。通过采用更高阶的阵列泵浦，所提出的方法可扩展用于高功率 SLM 阵列激光器。

2 × 2 arrayed, single-longitudinal-mode 1064-nm Nd:YVO4 laser with Dammann array pumping

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.
