Analysis of multilayered hologram properties by coupled waves method

Peculiarities of light diffraction on multilayered holograms have been analyzed based on the coupled waves theory. For such holograms, oscillations with periods determined mainly by distances between subholograms are observed in the dependence of diffraction efficiency on incident angle. If a refractive index modulation efficiency for two-layered holograms is more than a definite quantity then it is possible to match an incident angle for each wavelength of a definite range (i.e. 0.4 . . . 0.8 mkm) and the diffraction efficiency at such an angle is 100% and it does not have to be a Bragg angle. Such multilayered holograms can be used in laser technology for wavelength selection instead of the Fabry-Perot interferometer in semiconductor laser frequency stabilization devices, and for small angle displacement measurements.
