Title:
SOLID-STATE LASER DEVICE AND SOLID-STATE LASER PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/057367
Kind Code:
A1
Abstract:
This solid-state laser device (1) comprises a seed light source (10), a solid-state amplifier (20), a stimulated Raman scattering generation element (30), and a wavelength filter (40). The seed light source (10) outputs pulse light (LS) having a first wavelength. The solid-state amplifier (20) has a solid-state active medium (21) that outputs amplified pulse light (L0) having the first wavelength, the amplified pulse light (L0) being obtained by amplifying the pulse light (LS). The stimulated Raman scattering generation element (30) is disposed at a stage following the solid-state amplifier (20), the stimulated Raman scattering generation element (30) converting the amplified pulse light (L0) to a second wavelength at a wavelength conversion rate of 1% or greater through stimulated Raman scattering and outputting first pulse light (L1) having the first wavelength and second pulse light (L2) having the second wavelength. The wavelength filter (40) isolates the second pulse light (L2), using the difference in wavelength, from the optical path of the first pulse light (L1) outputted from the stimulated Raman scattering generation element (30).
