Abstract

A method for stabilizing the center frequency drift of a diode laser is described. The method employs electronic feedback of the frequency error signal and utilizes an in-fiber Bragg grating Fabry-Perot interferometer as a frequency discriminator. The measured standard deviation of the frequency drift of the heterodyne beat signal of two lasers was less than 16 MHz in a time of 2.5 h.
