Abstract

We reporte and demonstrate a solid-state laser to achieve controlled generation of order-switchable cylindrical vector beams (CVBs). In the cavity, a group of vortex wave plates (VWPs) with two quarter-wave plates between the VWPs was utilized to achieve mode conversion and order-switch of CVBs. By utilizing two VWPs of first and third orders, the second and fourth order CVBs were obtained, with mode purities of 96.8% and 94.8%, and sloping efficiencies of 4.45% and 3.06%, respectively. Furthermore, by applying three VWPs of first, second, and third orders, the mode-switchable Gaussian beam, second, fourth, and sixth order CVBs were generated.
