Laguerre-Gaussian beam generation via enhanced intracavity spherical aberration.
Optics Express, 2021 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-

General formula for bi-aspheric singlet lens design free of spherical aberration. [PDF]
Applied Optics, 2018 In this paper, we present a rigorous analytical solution for the bi-aspheric singlet lens design problem. The input of the general formula presented here is the first surface of the singlet lens; this surface must be continuous and such that the rays ...
