High-power laser diodes with nonabsorbing mirrors.

Abstract

We succeeded in the phase locked operation of a 5-element GaAIAs diode laser array emitting 0.6W CW. The diodes use nonabsorbing mirrors (NAM's) for the suppression of catastrophic optical damage (COD) and a buried twin ridge substrate (BTRS) structure for the injection current confinement and for the stabilization of a transverse mode.
