Laser device with high oscillation efficiency |
摘要 |
A laser device comprises a laser medium, a semiconductor light-emitting element for exciting the laser medium, a reflecting surface surrounding the outer periphery of the laser medium along its optical axis, and an opening provided in a part of the reflecting surface for causing light from the semiconductor light-emitting element to be incident upon the laser medium. The laser device is improved further by providing a polarizing plate and a light guide between the light-emitting element and the laser medium and by deviating the optical axis of excitation light from the central axis of the laser medium.
