Abstract
A surface-type light amplifier device has an active layer of a light amplification section sandwiched between an n-type semiconductor cladding layer that is an n-type semiconductor layer and a p-type semiconductor multilayer reflecting mirror. The light amplification section is attached to a transparent substrate on the side of the n-type semiconductor cladding layer. A plurality of divided electrodes form electrical continuity relative to the p-type semiconductor multilayer reflecting mirror via a p-type cap layer provided on the reflecting mirror. An electrode forming electrical continuity relative to the n-type semiconductor cladding layer is connected to a wiring conductor provided on the surface of the transparent substrate. The device enables amplification of a single, uniform, large diameter beam and oscillation of a laser.
