Deskripsi

We demonstrate the first InGaN-LD-pumped room temperature and continuous-wave laser operation of a Pr<sup>3+</sup>: LiYF<sub>4</sub> crystal at 915 nm. A maximum output power up to 78 mW with a laser slope efficiency of about 17% is obtained. The round-trip optical losses are estimated to be about 0.45%, and the M<sup>2</sup> beam quality factors measured in x and y dimensions are about 1.07 and 1.04, respectively.
