    Abstract: A magnetically saturable laser rod (e.g. doped YIG) has one end cut at Brewster''s angle and is included in an optical cavity. Modulation is accomplished, via Faraday''s effect, by varying the direction of the rod magnetization and by using the Brewster''s angle face as the polarization sensitive element in the cavity. Light reflected out of the cavity at the Brewster''s angle face can be detected and used in a feedback sense to control the applied magnetic field.

    Abstract translation: 磁饱和激光棒(例如掺杂YIG)具有一个在布鲁斯特角度切割的端部,并且包括在光学腔中。 通过法拉第的影响,通过改变杆的磁化方向和使用布鲁斯特角面作为腔中的偏振敏感元件来实现调制。 可以在反馈意义上检测并使用在布鲁斯特角面处从腔体反射的光以控制所施加的磁场。
