Title:
LASER APPARATUS AND LASER PROCESSING MACHINE
Document Type and Number:
WIPO Patent Application WO/2023/203711
Kind Code:
A1
Abstract:
A laser apparatus (100) is provided with: a pulsed light source (1) that generates signal light (11); an excitation light source (2) that generates excitation light (12); and a plurality of laser media (4a, 4b) that are arranged in series in the optical path of the signal light (11) and are each excited by the excitation light (12) to amplify the signal light (11). The optical axis-direction length of the laser medium (4b) among the plurality of laser media (4a, 4b) that the signal light (11) from the pulsed light source (1) enters last is shorter than the optical axis-direction length of the laser medium (4a) among the plurality of laser media (4a, 4b) that the signal light (11) from the pulsed light source (1) enters first.
