Abstract

A Faraday isolator (FI) based on a new magneto-optical medium—Ce:TAG ceramics—has been fabricated and studied in experiments. Compensation of thermally induced depolarization in the FI increases the isolation ratio from 31 to 39 dB at the laser power of 300 W. Estimates predict stable operation of the device with kilowatt laser power.
