HIGH-POWER LOW-LOSS GRINSCH LASER

摘要

A GRINSCH laser having an asymmetric configuration wherein the optical confinement is weighted more to the n-doped multilayer region than to the p-doped multilayer region. The GRINSCH laser can emit laser light at a wavelengthλ= 976 nm over a broad area with a beam power of 11.4 W at a 12 A bias current and 20 oC heat sink temperature. Fabry-Perot and distributed Bragg reflector GRINSCH laser configurations are disclosed.
