We demonstrate an end-pumped Laguerre-Gaussian (LG) mode-selectable Nd:YVO4 laser utilizing enhanced intracavity spherical aberration. The cavity was designed to exploit strong spherical aberration generated by an expanded beam, incident on a short-focal-length lens, which enabled oscillation of cavity modes of different order. This compact-cavity laser could operate efficiently with high-order LG mode, with the order of this mode being selectively changed by simply adjusting the distance between the short-focal-length lens and the output coupler. Scalar LG modes from LG0,10 to up to LG0,33 were observed in the experiment. The output power of the LG0, 33 mode was 1.87 W under an absorbed pump power of 6.6 W. 2021 Optical Society of America under the terms of the OSA Open Access Publishing Agreement
