high powered lasers of substantially any wavelength produced by certain processes including the process of providing a structure comprising a substrate with an epi structure thereon comprising a gain region with multiple quantum wells , a mirror stack coupled to the gain region , and a conductive layer coupled to the mirror stack ; dividing the conductive layer into a conductive , central area and one or more dielectric , peripheral areas ; attaching a conductive plate to the conductive layer ; thinning the substrate to improve the passage of light therethrough to produce a substrate remnant ; and attaching an electrode to the substrate remnant .
