近年来,高功率1319 nm波长全固态激光器成为激光领域的研究热点之一,它可以广泛应用于光纤通信、激光医疗、频率转换、激光武器等领域。本实验室采用独特的双棒串接热补偿技术,通过对Nd:YAG激光晶体主振荡波长1064 nm及次振荡波长的抑制,实现了最高输出功率为1261 W的1319 nm波 In recent years, the high-power 1319 nm wavelength all-solid-state laser has become one of the hot spots in laser field. It can be widely used in the fields of optical fiber communication, laser medical treatment, frequency conversion, laser weapon and so on. In our laboratory, a unique double-rod series thermal compensation technique was adopted to achieve the 1319 nm wave with the maximum output power of 1261 W by suppressing the main oscillation wavelength of 1064 nm and the sub-oscillation wavelength of Nd: YAG laser crystal
