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.
我们报告了采用一种新的泵浦方案，在红色、橙色和绿色光谱区域实现了掺Pr³⁺的LiLuY₄、LiYF₄和KY₃F₁₀单晶的连续波（CW）激光运转。泵浦源是一台特别研制的紧凑、稍可调谐且腔内倍频的二极管泵浦Nd:YAG激光器，在469.12 nm处输出连续波功率0.9W。在该泵浦波长下，观察到了对应于Pr³⁺的³P₀→³F₂、³P₀→³H₆和³P₁→³H₅跃迁的高效室温激光发射。虽然掺Pr:LiYF₄在红色区域获得了45%的最大斜率效率，但首次展示了掺Pr:KY₃F₁₀在约610 nm处的橙色激光运转。
