Laser device manufacturing method

The invention provides a laser device manufacturing method, which comprises the steps of: growing an active layer on a substrate; etching the active layer and the substrate to form two protruding table facets having a set spacing distance; growing reverse PN junctions on two sides of the two table facets, and covering the PN junctions on two sides of the active layers of the two table facets; growing a cladding used for light limitation on the PN junctions and the active layers of the two table facets; growing a contact layer used for electrical contact on the cladding; etching the contact layer, the cladding, the reverse PN junctions and the substrate to form isolation trenches on both sides of the two table facets; and manufacturing electrodes to form two laser units. The laser device manufacturing method can improve the yield of laser devices, and reduce the manufacturing cost of the laser devices. 本发明提供种激光器的制造方法，包括：在衬底上生长有源层；对有源层和衬底进行刻蚀，以形成凸出的且具有设定间隔距离的两个台面；在两个台面的两侧生长反向PN结，并使反向PN结覆盖两个台面的有源层的两侧；在反向PN结和两个台面
