Direct vortex emission from lasers typically grants access to efficient, large power, and pure mode generation. In this work we show a concise, unidirectional NdYVO4 band laser with an intracavity wedge-plate shearing interferometer (WPSI) as an output coupler, which converted the inner Gaussian mode to LG01 (Laguerre-Gaussian OV) output. It directly generated a watt-level LG01 OV with high mode purity (98%) in a single longitudinal mode. The monolithic WPSI features advantages in s
