Document Type and Number:
WIPO Patent Application WO/2022/215424
Kind Code:
A1
Abstract:
A high-temperature tank (116) includes an optical window which transmits a laser (132) and is provided at one end, and a right-angle conical mirror (102) which is provided at the other end, has an opening (106) at the apex and which reflects laser light (132) incident from the optical window towards the one end in an area other than the opening (106). A magnetic field generator (112) generates a magnetic field in the region of intersection of the laser reflected by the right-angle conical mirror (102). A magnetic field gradient relaxation module (130) generates a relaxation magnetic field which relaxes the gradient of the magnetic field generated by the magnetic field generator (112).
