摘要：

To maximize output with low vertical divergence of single emitter laser diodes, epitaxial structures were designed and fabricated with two types of waveguide structures. At a driving current of 27 A under room temperature, high power of 27.9 W and high efficiency of 66.5% was achieved. The vertical far-field divergence angle with 95% power intensity of 47 degrees was obtained. The aging test with temperature acceleration passed 3,500 hours without failure.
