报道了采用一种新的抽运方案，在红、橙子和绿色光谱区对掺Pr ~（3+）的LiLuY_4、LiYF_4和KY_3F_（10）单晶进行连续激光运转的结果。泵浦源是一个特别开发的紧凑型，轻微可调谐和腔内倍频二极管泵浦的Nd：YAG激光器提供了0.9W的连续输出功率在469.12 nm。在此泵浦波长下，观察到了与3 P0 → 3F 2，3 P0 → 3 H6和3 P1 → 3 H5 Pr 3+跃迁相对应的高效室温激光发射。当Pr：LiYF 4在红光中获得45%的最大斜率效率时，首次演示了Pr：KY 3F 10在约610 nm处的橙子激光操作。
We report continuous-wave (CW) laser operation of Pr3+-doped LiLuY4, LiYF4 and KY3F10 single crystals in the Red, Orange and Green spectral regions by using a new pumping scheme. The pump source is an especially developed compact, slightly tunable and intracavity frequency-doubled diode-pumped Nd:YAG laser delivering a CW output power of 0.9W at 469.12 nm. At this pump wavelength, efficient room temperature laser emissions corresponding to the 3P0→3F2, 3P0→3H6 and 3P1→3H5 Pr3+ transitions are observed. While a maximum slope efficiency of 45% is obtained in the red with Pr:LiYF4, the demonstration is made for the first time of the orange laser operation of Pr:KY3F10 at about 610 nm.
