抽象的。报道了一种具有单频和双波长激光输出的单片式Ho：YAG非平面环形振荡器(NPRO)。用1907 nm Tm：YLF激光共振泵浦Ho：YLFNPRO。在单频运转时，输出功率为3.09 W，斜率效率为61%，相对于抽运功率的光学效率为48%。用最大泵浦功率的Ho：YAGNPRO获得了高达10W的2091和2097 nm双波长激光输出，斜率效率相对于泵浦功率为61%。
Abstract. A resonantly pumped monolithic Ho:YAG nonplanar ring oscillator (NPRO) with single-frequency and dual-wavelength laser outputs is demonstrated. The Ho:YAG NPRO is resonantly pumped by a 1907-nm Tm:YLF laser. In single-frequency operation, the output power is 3.09 W, with a slope efficiency of 61% and an optical efficiency of 48% with respect to the pump power. Up to 10 W dual-wavelength laser output at 2091 and 2097 nm is also obtained from the Ho:YAG NPRO with the maximum pump power, with a slope efficiency of 61% with respect to the pump power.
