润色下面这段话：创新点说明：1 不同于之前研究常用的波长为785nm LD抽运源我们采用的抽运源波长为780nm。这种选择可以保证在较大范围驱动电流内晶体棒内抽运光仍能保持均匀分布有利于高功率输出。2 设计的单个激光模块采用了单通道水冷方式对晶体和LD在同一温度下进行冷却既能保证冷却效果又能缩减装置体积提高了此激光系统的实用性。3 此次研究的TmYAG激光器的谐振腔腔长是所有报道中最短的装置结构紧

Innovation points:

Unlike the commonly used 785nm LD pump source in previous studies, we have chosen a 780nm pump source. This choice ensures that the pump light within the crystal rod can maintain a uniform distribution over a wide range of driving currents, which is beneficial for high-power output.
The designed single laser module uses a single-channel water cooling method to cool both the crystal and LD at the same temperature. This not only ensures cooling efficiency but also reduces the device volume, improving the practicality of this laser system.
The resonator cavity length of this Tm:YAG laser in our study is the shortest among all reported studies, making the device structure compact and reliable.
The cooling temperature of this Tm:YAG laser system in our study is 12℃, which is higher than all previous reported hundred-watt level Tm:YAG lasers. This avoids the problem of crystal damage caused by end-face condensation at low cooling temperatures, improving the system's reliability and practicality. Additionally, at this temperature, the system's slope efficiency of 32.7% is the highest among all reported studies
