METHOD FOR MEASURING LASER FREQUENCY NOISE
Abstract
The features and problems of main approaches for measuring laser frequency noise are analyzed. A method is proposed, in which an unbalanced fiber-optic interferometer is used. At the output of the interferometer, a sub-carrier frequency signal modulated by laser frequency fluctuations is formed and the signal spectrum is measured. The proposed approach is relatively simple and affordable and does not require the use of rare specialized devices and complex specific procedures.
