翻译下面这段话为英语：道了一种高功率紧凑稳定的激光二极管LD侧面抽运的棒状TmYAG固体激光器。使用三个780nm波长的LD组成的激光模块对双端键合的TmYAG进行侧面泵浦从而实现高功率激光输出。为了减小装置体积搭建了对称平直短腔并且采用了单通道水冷方式。在冷却温度为12℃时获得了最高119 W 202 μm连续激光输出光-光转换效率为18斜效率高达327。 该系统能够在2h内保持最大功率稳定输出

A rod-shaped Tm:YAG solid-state laser pumped from the side by a high-power, compact, and stable laser diode (LD) was introduced. The Tm:YAG crystal was double-end bonded and pumped from the side by a laser module consisting of three LDs with a wavelength of 780nm, achieving high-power laser output. To reduce the device size, a symmetrical straight short cavity was built, and a single-channel water cooling method was used. The highest continuous laser output of 119 W at 2.02 μm was obtained at a cooling temperature of 12℃, with an optical-to-optical conversion efficiency of 18% and a slope efficiency of up to 32.7%. The system can maintain maximum stable output power within 2 hours, with power fluctuations of less than 1%. The beam quality factors in the x and y directions were measured to be 21.01 and 21.68, respectively
