We demonstrate a single-longitudinal-mode Ho:GdVO₄ continuous-wave (CW) laser at 2048.6 nm. We achieved excellent single-longitudinal-mode performance using a unidirectional ring cavity with an isolator and a half-wave plate. We obtain the maximum output power equal to 965 mW corresponding to a slope efficiency of 12.7%.

2μm单纵模Ho：GdVO 4 CW激光器

我们演示了在2048.6 nm处的单纵模Ho：GdVO ₄连续波（CW）激光器。我们使用带有隔离器和半波片的单向环形腔实现了出色的单纵模性能。我们获得等于965 mW的最大输出功率，对应于12.7％的斜率效率。
