Large-aperture Faraday isolator based on a terbium gallium garnet crystal

Not Accessible

Your library or personal account may give you access

Abstract

Unique Faraday isolator based on a TGG single crystal with aperture diameter of 40 mm for high average power lasers has been fabricated and investigated experimentally. The device provides a stable isolation ratio over 30 dB for large-radius laser beams with kilowatt average power radiation typical for high-power applications.
