摘要
A vortex laser generation device in a degenerate cavity with a spiral phase element and a vortex laser generation method are provided. The vortex laser generation device has a degenerate cavity, and the degenerate cavity has a resonator mirror, a gain medium, an optical element, and an output coupler. The off-axis beams are formed in multiple pass transverse modes to resonate by disposing an optical element in the degenerate cavity, so that a vortex laser with orbital angular momentum can be generated.
