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.

摘要

一种基于新型磁光介质——铈掺杂钛酸镓钇（Ce:TAG）陶瓷的法拉第隔离器（FI）已被制造出来并进行了实验研究。在300瓦激光功率下，对该法拉第隔离器中热致去极化的补偿将隔离比从31分贝提高到了39分贝。据估计，该器件在千瓦级激光功率下能稳定运行。
