在准连续808 nm半导体激光器端面泵浦下，无序Nd：LiGd（WO4）2激光晶体在自由运转和主动调Q两种模式下均获得了高效率的激光运转。同时获得了1.06 μm附近的多波长发射。在自由运转状态下，获得了0.63W的激光输出，斜率效率为40.6%。当重复频率为40 kHz时，获得了最大平均输出功率0.43 W和斜率效率30.2%的激光输出。这一工作表明Nd：LiGd（WO4）2是一种很有前途的激光晶体，可用于太赫兹、锁模和可调谐激光器的应用。
An efficient laser operation of disordered Nd:LiGd(WO4)2 laser crystal, end-pumped by a quasi-CW 808 nm diode laser, has been demonstrated in both free-running and actively Q-switched modes. Multi-wavelength emission around 1.06 μm was obtained simultaneously in this paper. In free-running status, 0.63 W laser output was obtained, giving a slope efficiency of 40.6%. When the repetition rate was 40 kHz in Q-switched operation, a maximum average output power of 0.43 W and a slope efficiency of 30.2% were obtained. This work indicated that Nd:LiGd(WO4)2 could be a promising laser crystal for THz, mode-locked and tunable laser applications.
