FARADAY ROTATOR, OPTICAL ISOLATOR, LASER APPARATUS, AND EXTREME ULTRAVIOLET LIGHT GENERATION APPARATUS

摘要

A Faraday rotator (100A) may include a magnetic field forming section (101,102) configured to form a magnetic field at a predetermined magnetic flux density in a predetermined region, a Faraday element (110) disposed in the predetermined region, and a first heat exhaust member (111), disposed on the side of one primary plane of the Faraday element, configured to form an optical contact surface with the Faraday element and configured to allow light (L12) at a predetermined wavelength to pass.
