We demonstrate a C-band wavelength-tunable microlaser with an -doped high quality (∼1.8×10) lithium niobate microdisk resonator. With a 976 nm continuous-wave pump laser, lasing action can be observed at a pump power threshold lower than 400 µW at room temperature. Furthermore, the microdisk laser wavelength can be tuned by varying the pump laser power, showing a tuning efficiency of ∼-17.03/ at low pump power below 13 mW, and 10.58 pm/mW at high pump power above 13 mW.
我们展示了一种采用掺铒高质量（约1.8×10）铌酸锂微盘谐振器的C波段波长可调谐微激光器。使用976纳米连续波泵浦激光器，在室温下，泵浦功率阈值低于400微瓦时即可观察到激光作用。此外，通过改变泵浦激光功率可对微盘激光器的波长进行调谐，在低于13毫瓦的低泵浦功率下，调谐效率约为-17.03皮米/毫瓦，在高于13毫瓦的高泵浦功率下，调谐效率为10.58皮米/毫瓦。
