摘要	The sensitivity to light returned near to the exit aperture (17) of a semiconductor laser is reduced by depositing onto the output face of said laser a layer (17) of opaque material. When the laser is first powered up, its output ablates the opaque material from the light exit aperture.
其他摘要	通过在所述激光器的输出面上沉积不透明材料层（17），降低了对靠近半导体激光器的出口孔（17）返回的光的灵敏度。当激光器首次通电时，其输出会从光出射孔消融不透明材料。
主权项	A process for fabricating a semiconductor laser (1), characterized in that it comprises the steps of depositing a layer (16) of opaque material on said laser output facet, and powering on said laser, whereby said opaque material is ablated from the light exit aperture of said laser.
