A diode-pumped tunable CW Nd(3+):LGS laser at quasi-three-level has been demonstrated. The output power up to 403 mW at the central wavelength of 904 nm was obtained, corresponding to a slope efficiency of 29.7%. Taking advantage of the broad emission spectrum of the disordered crystal Nd:LGS, we tuned the laser wavelength within the spectral range of 899.8 to 906.6 nm with an etalon inserted into the V-type cavity. To the best of our knowledge, it is the first time to obtain a tunable laser based on the (4)F(3/2)-(4)I(9/2) transition of Nd(3+)-doped crystals.
已演示了一种基于准三能级的二极管泵浦连续可调谐 Nd(3+):LGS 激光。在中心波长为 904nm 时，获得了高达 403mW 的输出功率，对应的斜率效率为 29.7%。利用无序晶体 Nd:LGS 的宽发射谱，我们在插入法布里-珀罗腔的标准具的作用下，在 899.8nm 到 906.6nm 的光谱范围内调谐了激光波长。据我们所知，这是首次基于掺 Nd(3+)晶体的(4)F(3/2)-(4)I(9/2)跃迁获得可调谐激光。
