Tm-doped sesquioxides, Tm:YScO, and Tm:LuScO crystals, were successfully fabricated by using a laser floating zone method. For the first time, continuous-wave laser operation at 2.3 µm on the H → H Tm transition of the two crystals was reported. Pumped by a 793 nm fiber-coupled laser diode, the Tm:YScO and Tm:LuScO lasers generated the maximum continuous-wave laser output power of 665 mW and 872 mW at 2.3 µm with a slope efficiency of 9.5% and 16.1%, respectively.
采用激光悬浮区熔法成功制备了掺铥倍半氧化物、Tm:YScO和Tm:LuScO晶体。首次报道了这两种晶体在2.3μm波长下基于H→H铥跃迁的连续波激光运转。由793nm光纤耦合激光二极管泵浦，Tm:YScO和Tm:LuScO激光器在2.3μm波长下分别产生了665mW和872mW的最大连续波激光输出功率，斜率效率分别为9.5%和16.1%。
