Summary:A laser apparatus may comprise: a substrate having a first surface and a second surface opposite to the first surface; a light emitting region formed on the first surface of the first substrate, the light emitting region including a p-type semiconductor layer and an n-type semiconductor layer; a p-contact layer formed on the p-type semiconductor layer; an n-contact layer formed on the n-type semiconductor layer; a sub-mount formed on the p-contact layer and the n-contact layer, the sub-mount including a first patterned dielectric coating layer formed on the p-contact layer and a reflector formed on the patterned dielectric coating layer.
