We report on, to the best of our knowledge, the first growth, spectroscopy, and laser operation of monocrystalline Ba(YLu)F doped with 1.25 at.% of Pr ions (Pr:BYLF). We studied the spectroscopic properties of this material, particularly in comparison with its isomorph Pr: BaYF (Pr:BYF). Under diode-pumped excitation, we achieved continuous-wave laser operation in the orange, red, and deep red regions in the three possible crystal orientations. We obtained considerably improved laser performances and remarkably low passive losses, in comparison with Pr:BYF crystals and other fluorides, indicating that Pr:BYLF is an excellent host material in the visible region.
据我们所知，我们首次报道了掺有1.25原子百分比Pr离子（Pr:BYLF）的单晶Ba(YLu)F的生长、光谱特性及激光运转情况。我们研究了这种材料的光谱特性，特别是与同构的Pr:BaYF（Pr:BYF）进行了比较。在二极管泵浦激发下，我们在三种可能的晶体取向中实现了橙色、红色和深红色区域的连续波激光运转。与Pr:BYF晶体和其他氟化物相比，我们获得了显著改善的激光性能和极低的无源损耗，这表明Pr:BYLF是可见光区域的一种优异基质材料。
