In order to explore the generation conditions and change factors of the vortex hollow beam in the end-pumped Nd∶YVO4 microchip laser, a new method of generating ring pump light based on the axicon-lens group was constructed. The pump light was simulated and analyzed by ZEMAX, and the mode matching calculation was performed based on the thermal effect analysis. The output of the ring pump light and the ring hollow laser were successfully obtained through the experiment, and the output light was verified by the experiment as the first-order vortex light. The results show that the method can generate 808nm pump light with controllable beam size, and its spot radius can change rapidly with the relative position of the axicon tip and the focal plane of the lens. At the same time, the pump lightgenerated by this method can make the microchip laser with a cavity length of 300μm output a stable 1064nm first-order Laguerre-Gaussian vortex hollow beam. This research result has important guiding significance for the establishment of the actual method of microchip laser output vortex hollow beam.
