摘要: A semiconductor laser chip has an emission facet for emitting a beam. sub-mount first surface and at least one second vertical to the surface. The is provided on of sub-mount. arranged in line with inclined angle 3 30 degrees. reflects reflection light sub-beam diffracted from main beam emitted by chip.
