A Single Fiber Coupling Technique for High Power Diode Laser Arrays
-
Abstract
This paper reports two pairs of laser diode arrays (LDA) with wavelengths of 808 and 980nm,respectively,whose beams were mixed into a single fiber using step-mirror beam-shaping technology,polarization,and wavelength coupling technology.As a result,a single fiber optic coupling module of LDA was achieved,of which the output power is 95.8W,maximal coupling efficiency is more than 60%,the diameter of the fiber core is 400μm,and NA is 0.22 -
