环形光腔锁模控制

Controlling mode locking in optical ring cavities

G. Krenz, S. Bux, S. Slama, C. Zimmermann, Ph. W. Courteille

摘要:

光学环形谐振器的腔内元件的表面中的缺陷可以将光从一个模式散射到反向传播模式中。由这种反向散射引起的腔模式的锁相是众所周知的例子,其众所周知地折磨激光陀螺仪和类似的有源系统。我们的实验表明,如何反向散射可以规避在一个单向操作的环形腔的谐振腔模式的适当选择或主动反馈控制。

英文摘要:

Imperfections in the surface of intracavity elements of an optical ring resonator can scatter light from one mode into the counterpropagating mode. The phase-locking of the cavity modes induced by this backscattering is a well-known example that notoriously afflicts laser gyroscopes and similar active systems. We experimentally show how backscattering can be circumvented in a unidirectionally operated ring cavity either by an appropriate choice of the resonant cavity mode or by active feedback control.
