Holger Mueller, Achim Peters, Claus Braxmaier

摘要:

我们提出了一种简单的方法来稳定的光纤的光路长度的激光波长的约1/100的精度。我们研究的路径长度调制的导电加热层的光纤的动态响应。通过使用Pound-Drever-Hall方法相对于激光波长测量路径长度;通过加热器施加负反馈。我们将该方法应用在低温谐振器频率标准的上下文中。

英文摘要:

We present a simple method to stabilize the optical path length of an optical fiber to an accuracy of about 1/100 of the laser wavelength. We study the dynamic response of the path length to modulation of an electrically conductive heater layer of the fiber. The path length is measured against the laser wavelength by use of the Pound-Drever-Hall method; negative feedback is applied via the heater. We apply the method in the context of a cryogenic resonator frequency standard.
