Abstract:
A high-powered mid-IR antimonide-based unstable resonator semiconductor laser that is optically pumped. One Fabry-Perot facet is a mechanically polished cylindrical mirror that extends well into the GaSb substrate. The waveguide is designed to weakly confine the transverse optical mode, and the optical pump stripe width can be varied to optimize the cavity width for high brightness operation.
