ABSTRACT
We comparatively study an InGaN laser-diode-pumped continuous-wave laser at â¼607 nm (σ polarization) using differently doped PrLiYF4 single crystals. Maximum output power and slope efficiency at this wavelength were up to 209 mW and 47.1%, respectively, using a 0.2 at. % doped and 8 mm sample. Findlay-Clay analysis shows roundtrip losses, including reabsorption loss at this particular emission of about 1.2% using the 0.2 at. % doped sample, which is lower than that of samples with higher doping concentrations at 0.5 and 1 at. %. Using a 0.15 mm glass plate as a Fabry-Perot etalon, a maximum output power of 73 mW was achieved at â¼604 nm (π polarization) with slope efficiency of 17.2% for what is believed to be the highest result currently.
