H01S5/164 - CPC Classification

Classification description:

Semiconductor lasers; Construction or shape of the optical resonator, e.g. extended or external cavity, coupled cavities, bent-guide, varying width, thickness or composition of the active region; Window-type lasers, i.e. with a region of non-absorbing material between the active region and the reflecting surface with window regions comprising semiconductor material with a wider bandgap than the active layer
