Mirror system for uniform beam transformation in high-power annular lasers
Abstract
A technique employing geometric optics has been used to determine the mirror arrangements that will transfer radiation with uniform intensity from an outer annulus to a central cylindrical beam. The resulting configuration is applicable to mode control in high-power lasers. The mirror shapes require only moderate curvature and do not present fabrication difficulties with the exception of the narrow rim of the outer mirrors which reflects towards the axis.
