Description

 Experimental samples of two types of photonic crystal anglular selectors for use in compact high-brightness solid-state lasers have been developed and manufactured. Modeling and optimization of parameters of photonic crystal structures for angular filtration and experimental research of their characteristics are carried out. The developed axisymmetric diffraction angular selector will provide high quality of a beam of compact wide-aperture lasers with a semiconductor modulator. Its optimal parameters were determined, and prototypes were made and the calculated characteristics were experimentally confirmed. The developed one-dimensional angle selector based on multilayer metal-dielectric structures has a narrow reflection peak with a width of 10 to 0.1 mrad and the configuration of the dielectric layers has been optimized. Prototypes of this type of selectors were made and the calculated characteristics were experimentally confirmed. A solid-state laser using angular selectors that generates a beam with a wide aperture with a given angular difference is developed. Such lasers can be promising for use in guidance systems where high quality laser beam is required.
