Abstract
A new facet coating material for high power diode lasers will be developed that reduces interface states at the cleaved facet and increases facet cooling. The facet coating is expected to be more robust and lead to increased power and brightness in high power diode lasers, bars and stacks. The facet coating technique makes use of commercial processes based on vacuum cleaving and epitaxial growth, and can be used to add optical elements to improve beam quality and spectral control.
