Collimated Laser Beam Expander Design and Simulation

LI Jian-xin

Abstract

Through breathes out Hartmann spherical-aberration automatic measurement collimation which resolved collimated(parallel) beam of departure,based on the Gaussian optics theory,Analyse the large collimated beam expander magnification Principle through the project angle。Achieve a change in laser beam diameter and divergence angle of the beam expander collimator system design,and has been verified through the simulation to meet the optical system aberration measurement requirements Hartmann spherical-aberration measurement.
