Abstract
A vortex kinoform mode converter which transforms a zero order Hermite-Gaussian laser mode to first order Laguerre-Gaussian mode with screw phase dislocation has been demonstrated. The kinoform element imitating mathematical helicoid surface has been fabricated in fused silica substrate with using wet chemical etching. Conversion efficiency >90% for high power laser beams has been achieved in testing experiments.
