Abstract

Continuous-wave (CW) cyan and deep-ultraviolet lasers at 488 nm and 244 nm were realized using a Pr³⁺:YLF crystal. A folded V-type resonator with a Brewster-angle birefringent plate generate single-line oscillation at 488 nm, producing a maximum output power of 342 mW under 15 W diode pumping. Intracavity frequency doubling with a 3-mm BBO crystal generates 244 nm radiation, achieving 62 mW of output. This work represents the first demonstration of CW Pr³⁺:YLF laser emission at 488 nm and its extension to 244 nm, offering a compact approach for blue-cyan and deep-UV sources.

Pr：基于ylf的青色和深紫外激光源在488nm和244nm

利用Pr³+:YLF晶体实现了488 nm和244 nm的连续青色和深紫外激光器。折叠v型谐振腔与布鲁斯特角双折射板在488nm处产生单线振荡，在15w二极管泵浦下产生最大输出功率342 mW。腔内倍频与一个3毫米BBO晶体产生244nm的辐射，实现62兆瓦的输出。这项工作首次展示了488 nm的连续波Pr3+:YLF激光发射，并将其扩展到244 nm，为蓝蓝色和深紫外光源提供了一种紧凑的方法。
