研制了一种工作在2微米光谱区附近的高效室温单频激光器耦合腔。当吸收泵浦功率为2.4W时，获得了稳定的721 mW的1991 nm单纵模振荡，光-光转换效率为30%，斜效率为46%。获得了5 nm的频率调谐范围和稳定的输出功率。光束传输因子M2在x和y方向上分别为1.43和1.42。
A coupled resonator was developed for high efficient room-temperature single-frequency laser operating near 2 mum optical spectral region. 721 mW stable single-longitudinal-mode oscillation at 1991 nm was obtained when the absorbed pumping power was 2.4 W. The optical-to-optical efficiency was 30%, and the slope efficiency was 46%. 5 nm of frequency tuning range was obtained with stable output power. The beam propagation factors M2 were 1.43 and 1.42 in x and y directions, respectively.
