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