摘　　要：在环形激光器中,我们采用布氏偏振片作为输出境,并将其一个方向传播的波反馈回另一个方向传播的波,使环形激光器的输出单向性、输出功率和输出偏振特性都较文献有所改善。在此基础上进一步改进,提出偏振反馈单向行波环形激光器。We report here an improved unidirectional travelling-wave laser operation mechanism. A Brewster polarized film is used both as the output coupler in one direction and as the feedback coupler in another direction. A better unidirectional property is obtained.Mean-while, a more effective unidirectional operation mechanism,i.e, using an amplified feedback signal to couple into the laser cavity, is proposed.
