The method and apparatus is for frequency stabilizing and wavelength scanning of the lazer by sensing spatial movement of interference patterns of an etalon. The apparatus comprises a beam splitter (3) making part of lazer beams (4) incident over the temperature stabilized etalon (5); an electric circuit (6) generating feedback signals of the interference patterns (9) incident over the linear photodiode array (1); a pneumatic control device (7); a diffraction grating (8) control device; a lazer resonator (2).
