LD-pumped high-power CW Pr3+:YLF Laguerre-Gaussian lasers at 639 nm

Xiuji Lin et al.

Summary: High-power continuous-wave lasers at 639 nm were obtained by LD pumping on a lowly-doped Pr3+:YLF crystal, achieving output powers of 8.14 W for quasi-fundamental mode laser and 6.03 W for vortex lasers. The results provide theoretical guidance for designing high-power Laguerre-Gaussian lasers.

Tunable continuous-wave dual-wavelength laser operation of Pr3+:LiYF4 around 900 nm

Jiaxin He et al.

Summary: In this study, the first tunable continuous-wave simultaneous dual-wavelength laser operation of a Pr3+:LiYF4 crystal in the 900 nm spectral range using a single birefringent filter (BF) was achieved by adjusting the rotation angle of the BF. CW simultaneous dual-wavelength lasers operating at 869 and 915 nm, 894 and 915 nm, 915 and 923 nm were obtained respectively.
