High-Precision Modal Decomposition of Laser Beams Based on Globally Optimized SPGD Algorithm
We propose a globally optimized stochastic parallel gradient descent (SPGD) algorithm to analyze the modal content of laser beams with high precision. Modal decomposition (MD) based on conventional SPGD algorithms often falls to a local minimum when a laser beam consists of six or more fiber eigenmo...
