Abstract

In this paper, higher-order modes were generated using a diode-pumped solid-state digital laser operating at 532 nm (visible) wavelength. We inserted a non-linear crystal (potassium titanyl phosphate, KTiOPO₄ or KTP) inside the laser cavity operating at 1064 nm (Near-IR). The KTP was pumped using higher-order laser modes generated by the 1064 nm solid-state digital laser. We generated Laguerre-Gaussian laser modes and Hermite-Gaussian laser modes inside a cavity. The laser modes were characterised by analysing the intensity distribution.
