Paper Abstract

By using optical signals obtained by a high-contrast saturated absorption spectrometer as a reference frequency selector, a diode laser frequency has been locked to the hyperfine transition line of Cs atom. We did not use a mirror but a grating in order to exclude feedback of unwanted side modes, which cause mode hopping or oscillating an unwanted frequency whose intensity is not decreased even though passing through the atomic cell two times. Long term stabilization has been accomplished by compensating the cavity length for phase fluctuations.
