Abstract
Section titled “Abstract”Abstract This work report the generation of high‐order Laguerre-Gaussian (LG) modes from a nanosecond, optical vortex pumped diamond Raman laser. This system is capable of generating first‐Stokes ( λ 1st = 1240 nm) LG modes with topological charge (ℓ) of up to 26 and second‐Stokes ( λ 2nd = 1485 nm) LG modes with topological charge of up to 22, when pumped using a first‐order vortex beam. The maximum first‐ and second‐Stokes LG mode energies are measured to be 0.5 and 1 mJ, respectively, when pumping with energy of 19.8 mJ.
