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 1st derivatives, obtained from F=1→F/=2 and a crossover resonance of F=1→F/=0,1 the stability was measured 2.2x10-12τ-1/2 @1s, decreased to 4.9x10-13τ-1/2 @150 s, and 2.5x10-12τ-1/2 @104 s integration times. The frequency stability 4.2x10-12τ-1/2, 3.5x10-13τ-1/2, 1.2x10-12τ-1/2 values were obtained at 1, 400, and 104 s integration times respectively by using the 3rd derivatives of the resonances |
