Abstract

One of the most important problems that exists relative to the longevity of semi-conductor lasers is optical facet erosion and damage. High optical fields appear to cause this damage at the mirror facets of these devices. The damage occurs over a period of use with a continual increase requirement of operating current and subsequent failure of the laser to lase.
