発明の名称 (英語) Q-SWITCH SOLID-STATE LASER DEVICE NEW
発明の概要(英語) A laser device using a solid-state laser material and an active Q-switch is reduced in size. In a laser device that uses a solid-state laser material and a Q-switch, a feature is present whereby the Q-switch is actively controlled using an electro-optic effect or an acousto-optic effect, but the laser device is increased in size. Reduced dimensions can be achieved when a magneto-optic effect is used for the Q-switch. A pulse laser can be obtained having a short duration and high peak intensity. By combining a permanent magnet and a coil, it is possible to reduce the current value for varying the Q-value.
特許請求の範囲(英語) [claim1]
1. The 1st resonance mirror and the solid state laser material and the Q switch and the 2nd resonance mirror, is arranged in the order,
The aforementioned Q switch, is formed with combination of the membrane and the magnetic flux generator which display the magneto-optical effect,
