Abstract:	A novel method of stabilizing laser frequency that uses a sub-Doppler spectrum of atoms in a thin vapor cell has been developed. The extended-cavity diode laser is frequency-locked to a hyperfine component of the Cs D₂ line. The linewidth and the signal-to-noise ratio of the spectrum are systematically investigated to find a cell length that gives best long-term frequency stability. In the Allan-variance measurements on the beat note between two lasers thus stabilized, a frequency stability of 6.2×10^-11 is achieved at an averaging time of 5 s. PACS 42.62.Fi, 42.60.Lh, 39.30.+w
