Acoustic-optical detector of gravitational waves based on high-quality crystals

A design of the detector of gravitational waves based on the optical interferometer with a crystal of high-quality acoustic and optical parameters as a sensitive element is analyzed. The gravitational wave frequency being 10 to the 7th power rad/sec, the maximum Brown noise sensitivity of the detector to the gravitational flux is shown to be able to attain 10 to the -2 to 10 to the -1 erg/sq cm/sec in the frequency band 2 x 10 to the -4 Hz.
