Title:
OPTICAL ELEMENT
Document Type and Number:
WIPO Patent Application WO/2023/243473
Kind Code:
A1
Abstract:
The purpose of the present invention is to realize a Faraday rotator that is small, inexpensive, and can withstand high-output and high-repetition laser radiation. An optical element (100) includes: a reflective Faraday rotation element (110) that rotates the polarization plane of reflected light with respect to the polarization plane of incident light; a magnet (130) provided on the opposite side of the plane onto which the incident light falls with respect to the Faraday rotation element; and a coolant circulation unit (140) and/or a cryostat (150) that cools the Faraday rotation element.
