SOLID-STATE LASER OSCILLATOR AND MACHINING APPARATUS USING THE SAME |
摘要 |
In a resonating-type solid-state laser oscillator including a solid-state element containing a laser active medium and providing a plurality of thermal lenses during excitation and reflecting mirrors arranged oppositely to each other on both sides of the solid-state element so that their optical axes are coincident to each other, a prescribed relationship is given among the refractive index and length of the solid-state element, the radii of curvature of the reflection mirrors, the distances between the reflecting mirrors and the solid-state element and the difference between plural thermal lenses by refringence of the solid-state element so that oscillation areas due to the plurality of thermal lenses are separated from each other.
