The arrays of phase-locked lasers

Abstract

Summary form only. Radiation parameters of 2D-arrays of waveguide CO/sub 2/-lasers synchronised by in-cavity spatial filter method are investigated. The dependencies for phase-locking efficiency and for axial brightness of far-field array radiation rationed to maximal value versus of number N of single lasers in an array, filter parameters and conditions of excitation are received. For all N phase-locking efficiency decreases if filter transparency also decreases because of increasing influences of additional filter introduced cavity radiation losses.
