Solid-state laser apparatus

摘要

A solid-state laser apparatus comprises a plurality of solid-state materials each having an active solid-state medium and arranged in a row with a predetermined space on an optical axis of light incident thereon. An optical rotation material and an angle adjusting instrument for adjusting an angle between the optical rotation material and the optical axis of incident light are disposed in at least a space selected from among the plural spaces. The laser apparatus further comprises a laser optical system for extracting a laser beam emitted by the plural solid-state materials.
