摘要

A diode-pumped continuous-wave (CW) orthogonally polarized Sm: YAlO3 (Sm: YAP) orange laser on 4G5/2→ 6H7/2 transition with output power ratio and wavelength tuning was demonstrated. By adjusting the tilt angle of the beam splitter (BS) and the rotation angle of the intracavity Lyot filters, multiple pairs of orthogonally polarized single-wavelength (OPSW) and dual-wavelength (OPDW) lasers were realized. The highest total output power with the OPSW orange laser at 604 nm reached 1.24 W at an absorbed pump power of 9.0 W at 405 nm, resulting in an optical-to-optical conversion efficiency of 13.8% with respect to the absorbed pump power. Besides, maximum balanced output power with the OPDW orange laser at 604 and 610 nm was 0.48 W, resulting in an optical-to-optical conversion efficiency of 10.7% with respect to the absorbed pump power. To the best of our knowledge, it is the first time to achieve Sm: YAP lasers.
