Abstract

We report on the stabilization of a semiconductor laser’s frequency, using spectra-controlled etalon. As the spectra of an etalon are controlled by one of the Rb absorption lines, they provide highly stable reference frequencies in a broad frequency range. When we adapted the PEAK method to the etalon’s spectra and used a Doppler-free absorption line of Rb atoms as the control signal for the newest model of our system, relative optical frequency stability of 2.91x10^-11≤σ(2,τ)≤3.72x10^-10 was achieved in averaging time for 0.04s≤τ≤100s.
