Power output optimization in complex laser systems by means of polarization control

Abstract

Recently, the polarimetricmethod for thermally-induced polarization changes driven power losses (TIPCL) mitigation in complex laser systems has been developed. However, the final optimization relied on the four-parameter numerical process. This letter provides a fully analytical direct calculation alternative to this optimization process. The validity of this approach is demonstrated on the previously published data from pulsed laser system Bivoj/DiPOLE100. The new approach provides a deeper insight into the polarimetric method for TIPCL suppression and also brings a more precise, reliable, and faster alternative to the numerical process used earlier.
