Abstract

A pair of special diffractive optical element (DOE) is used in the combining of six Nd:YAG lasers to obtain flat-top output beam. The function of this pair of DOE in the system has been discussed. The property of output beam distribution has been analyzed and simulated. Both the measured far field and near field intensity distributions match the simulated results. Combining output energy of 15.3J is obtained, and the transfer efficiency of the DOEs is about 81%.
