ABSTRACT
The generation of optical vortex beams with user-configurable topological charge and spatial profile is a topic intense research due to the numerous potential applications for these types laser beams. In this work, we demonstrate direct controllable tunable from Pr3+:YLF cavity using spot-defect technique. A theoretical model established examine relationship between generated beam how relates parameters. Experimentally, selective operation first- second-order lattices one four singularities at 607 nm can be achieved by adjusting position defect spot. This work offers insight into methods visible range applications.
