报道了在 1.01 µm 和 0.835 µm 波长下同时泵浦的 Pr3+ 掺杂氟锆酸盐光纤中 491 nm、520 nm、605 nm 和 635 nm 的连续波室温激光振荡。 635 nm 跃迁测得的输出功率为 185mW。获得的阈值表明，在优化的光纤中，所有四个跃迁的激光二极管泵浦操作应该是可能的。
Continuous-wave, room temperature laser oscillation at 491 nm, 520 nm, 605 nm and 635 nm in a Pr3+-doped fluoro-zirconate fibre pumped simultaneously at 1.01 µm and 0.835µm is reported. An output power of 185mW has been measured for the 635 nm transition. The thresholds obtained suggest that laser diode-pumped operation of all four transitions should be possible in an optimised fibre.
