A method of stabilizing frequency of a semiconductor laser is described. The method comprises stabilizing time- dependent frequency fluctuation by utilizing an absorption line of an isotope acetylene gas molecule. The method can be practiced with an apparatus for stabilizing frequency of a semiconductor laser, which comprises a semiconductor laser, an optical absorptional material, a photodetector and a control circuit as essential elements. The optical absorptional material has optical absorption characteristics utilizing an absorption line of an isotope acetylene molecule.
