  • Patent number: 5189677
    Abstract: The wavelength difference of two laser diodes is stabilized on a single Fabry-Perot interferometer. This stabilization is of such a quality that the application in the two-wavelength interferometry and two-wavelength holography is possible. In the Fabry-Perot interferometer, the light components may be distinguished by their polarization or may be spatially separated.
