The extended cavity diode lasers’ frequencies were stabilized by the usage of the 1st and 3rd derivatives signals obtained from hyperfine resonances of the 87Rb D2 line with the Zeeman modulation technique. By using the 3rd derivatives of the F = 1 → F/ = 2 and CO10–11 resonances 4.2 × 10−12 τ−1/2, 3.5 × 10−13 τ−1/2 and, 1.2 × 10−12 τ−1/2 frequency stability values were obtained at 1, 400 and 104 s integration times, respectively. Frequency stability measurements were also measured concerning derivative signals obtained from F = 2 → F/ = 3, CO21–23, and CO22–23 crossover resonances. The 1.4 × 10–12 τ−1/2 @1 s, 2.7 × 10–13 τ−1/2 @300 s, and 9.6 × 10−13 τ−1/2 @104 s frequency stability values were attained with using of 1st derivative of CO22–23, and CO21–23.
