Abstract

A new method of coherent summation of laser beams is proposed. Two-dimension numerical simulation based on the conjugate gradient algorithm shows that the combination efficiency is about 94.8%, and an error less than 2.4% with a 16-level phase quantized diffraction optical element. Error analysis has also been performed.
