摘要：
High-power, picosecond structured optical vortices with 2 and 4 phase singularities have been directly generated in an all-solid-state laser. Stationary two- and four- vortex arrays have been obtained in space by transverse mode-locking, and picosecond pulses have been generated by longitudinal mode-locking. The maximum output powers of the picosecond two- and four-vortex arrays were 3.7 and 3 W, and their pulse durations were similar to 16.2 and similar to 17.0 ps, respectively. This work provides a method for direct generation of structured optical vortices from the resonator, which have potential applications in particle manipulation, free-space optical communications, and nonlinear orbital angular momentum conversions.
