The article treats selective qualities of the second order space components with light-sound interaction under Bragg’s double angle in intermediate diffraction. The value of diffraction efficiency is estimated by mathematical calculation of the system of connected differential Raman-Nath equations using the method of continued fractions. There are given the results of the calculations of the diffraction efficiency for the components of the first and second orders dependent on ultrasonic frequency under the different values of wave parameter.
