Title:
Q-SWITCH STRUCTURE AND Q-SWITCH STRUCTURE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/250102
Kind Code:
A1
Abstract:
The present invention is a Q-switch structure which comprises a solid-state laser medium and a magnetic optical material, and in which the solid-state laser medium and the magnetic optical material are bonded and thereby integrated, wherein the thickness of the solid-state laser medium is at least 1mm, and the solid-state laser medium and the magnetic optical material are directly bonded. Due to this configuration, provided is a Q-switch that contributes to reducing the size of a laser device, and that can handle high optical output.
