Title Q-SWITCH SOLID-STATE LASER DEVICE 新技術説明会
Abstract 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.
Scope of claims [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,
When excited light incidence is done in the aforementioned solid state laser material, pulse is added to the aforementioned magnetic flux generator, the pulsed laser the Q switch solid state laser device which radiates.
[claim2]
2. The membrane which displays the aforementioned magneto-optical effect, the Q switch solid state laser device of the claim 1 which is selected from the membrane where Faraday angle of rotation 1 times or more changes with the magnetic flux change by the magnetic flux generator.
[claim3]
3. The membrane which displays the aforementioned magneto-optical effect, the claim the Q switch solid state laser device of 1 which is the rare earth iron garnet or 2.
[claim4]
4. The aforementioned magnetic flux generator, from the permanent magnet and the claim 1 which is formed with combination of the exciting coil in no 1 sections of 3 the Q switch solid state laser device of statement.
