摘要

获得高功率、高光束质量和高效率的激光源一直是固体激光技术的重要发展目标之一。然而，到目前为止，还无法直接从简单的固体激光器中获得无需液体冷却的百瓦 TEM00 模式（大体积）光束。为了克服这些挑战，我们在此提出了一种基于低热效应原理和功率叠加法的新方法。这样，在室温下，最简单的 Nd:YAG 激光器就能产生 131 W 的 TEM00 模式。重要的是，该激光器可长时间稳定工作（3 小时内均方根为 0.307%），增益介质由风扇冷却。该演示有望提升固态激光源的高功率和高光束质量应用。

Room temperature high-power TEM00 mode beam from bulk solid-state laser without water cooling

Obtaining high power, high beam quality, and high efficiency laser sources has always been one of the important development goals in solid-state laser technology. However, up to now, hundred-watt TEM₀₀ mode (large-volume) beams directly from simple solid-state lasers without liquid cooling are not available. To overcome these challenges, here we propose a new approach based on the principle of low thermal effect and the power superposition method. By doing so, at room temperature, a 131 W TEM₀₀ mode is obtained from the simplest Nd:YAG laser. Importantly, the laser can work stably for a long time (root mean square: 0.307 % over 3 h), and the gain medium is cooled by a fan. This demonstration promises to upgrade high-power and high beam quality applications for solid-state laser sources.
