Abstract

This letter presents an experimental study on generating ultra-high-order Laguerre-Gaussian (LG) modes in an Nd:YAG solid-state laser using annular pumping and an intracavity lens. The hollow structure of the annular pump beam effectively suppresses low-order modes, creating optimal conditions for high-order modes excitation. The intra-cavity convex lens enhances single-mode selection, enabling stable ultra-high-order petal-like LG _0,±l mode output. By adjusting the pump beam size and lens position, the highest angular indices l reached 375th order was achieved. This approach provides a novel method for high-order LG _0,±l mode generation in solid-state lasers, with potential applications in optical manipulation, optical communication, and related fields.
