Abstract

Tm-doped LuScO mixed sesquioxide ceramics were successfully fabricated by using a solid-state reactive sintering method. The absorption and emission spectra were measured at room temperature. Continuous-wave (CW) and passively Q-switched laser operation of Tm:LuScO ceramic were investigated for the first time to our knowledge. A CW output power of 211 mW with slope efficiency of about 8.2% was obtained. With single-walled carbon nanotube (SWCNT) as saturable absorber, a maximum average output power of 32 mW was achieved. The shortest pulse width was 0.59 μs at pulse repetition rate of 34.72 kHz.

摘要

采用固态反应烧结法成功制备了掺铥的LuScO混合倍半氧化物陶瓷。在室温下测量了吸收光谱和发射光谱。据我们所知，首次对Tm:LuScO陶瓷的连续波（CW）和被动调Q激光运转进行了研究。获得了211 mW的连续波输出功率，斜率效率约为8.2%。以单壁碳纳米管（SWCNT）作为可饱和吸收体，实现了32 mW的最大平均输出功率。在34.72 kHz的脉冲重复频率下，最短脉冲宽度为0.59 μs。
