Abstract

Optical heterodyne measurement of frequency stability of the 0.633 µm line in dual stabilization with the 3.39 µm line was carried out. The best stability in terms of Allan variance was 4.14×10−11 for averaging time τ=1 s and the long-term stability was 3.14×10−10 for τ=100 s. Decrease of the long-term stability appears mainly to be attributable to a difference of the temperature coefficients of the Brewster windows at each wavelength.
