Improved Beam Quality of Coherently Combined Angled-Grating Broad-Area Lasers

Improved Beam Quality of Coherently Combined Angled-Grating Broad-Area Lasers

We improve the beam quality and performance of coherently combined angled-grating broad-area lasers through current/gain confinement. We show that the nonuniform current/gain distribution in our previous lasers excites the second-order Bragg mode and degrades the beam quality. Ion implantation is us...
