We studied the properties of an annular waveguide laser resonator, performing a new set of numerical simulations. The existence of fractional-Talbot effects is shown and results are compared to previous free-space propagation calculations and experimental results. Our study allows us to design annular waveguide lasers efficiently extracting power into a well behaving field distribution, convertible into a high quality beam by means of simple optics.

Abstract
We studied the properties of an annular waveguide laser resonator, performing a new set of numerical simulations. The existence of fractional-Talbot effects is shown and results are compared to previous free-space propagation calculations and experimental results. Our study allows us to design annular waveguide lasers efficiently extracting power into a well behaving field distribution, convertible into a high quality beam by means of simple optics.File in questo prodotto:
