A system and method for scanning the wavelength of an external cavity laser uses synchronized angular motions of two mirrors. By adjusting the angular motions in a selected ratio, it is possible to change the lasing wavelength of the cavity without mode-hops. The mode-hop free ratio of angular motions is determined by simultaneously satisfying the conditions of wavelength selected by diffraction angle from a diffraction grating, and the length of the external cavity.
