| 摘 要： | 在稳频激光的光纤传输中,光纤本身引入的相位噪声影响到激光频率的稳定性,造成激光光谱的展宽。介绍了光纤相位噪声的测量及如何通过反馈控制在光纤远端消除这一噪声。建立了消除光纤相位噪声的实验系统,测量了一段30 m裸光纤引入的相位噪声,并采用反馈控制在光纤的远端消除这一噪声,将光纤造成的1 kHz谱线展宽减小到1 Hz以下。还分析了将相位检测中解调出来的噪声电压转换成相位噪声的问题。

| Abstract: | When a frequency stabilized laser pulse transmits through an optical fiber,the phase noise generated by the optical fiber affects the stability of the laser frequency,resulting in a broadened laser spectrum.The measurement and feedback control of phase noise at the remote site of an optical fiber are introduced.Experimental setups are introduced for the measurement and active cancellation of the phase noise due to optical fiber.Using feedback control,the original 1 kHz spectral line broadening introduced by... |
