Title:
Q-SWITCHED STRUCTURE AND METHOD FOR MANUFACTURING Q-SWITCHED STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2022/250101
Kind Code:
A1
Abstract:
The present invention provides a q-switched structure comprising a solid-state laser medium and a magneto-optical material, wherein the solid-state laser medium and the magneto-optical material are joined and integrated. A first adhesive-adapted antireflection film is formed on one surface of the solid-state laser medium. A second adhesive-adapted antireflection film is formed on one surface of the magneto-optical material. The first adhesive-adapted antireflection film of the solid-state laser medium and the second adhesive-adapted antireflection film of the magneto-optical material are adhered to each other with an optically transmissive material therebetween which is optically transmissive to a laser oscillation wavelength of a laser oscillated from the solid-state laser medium. Thus, a Q-switched structure that contributes to size reduction of a laser device and has high beam quality is provided.
