| Zusammenfassung: | 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. |
