摘要：
This report is about a continuous wave (CW) deep ultraviolet laser operation at 273 nm by intracavity frequency doubling of laser diode pumped Pr3+ doped LiYF4 lasers. We use two 3 W InGaN laser diodes, one 3 mm long Pr3+:LiYF4 (Pr:YLF) crystal and one 5 mm long beta-barium-borate (BBO) crystal, coherent radiation with an output power of 128 mW at 273 nm was obtained with a 2.9% optical to optical conversion efficiency. To the best of our knowledge, this is the first report detailing a Pr:YLF laser that emits light at 273 nm.
