A Study of the Response of Acousto-Optic Delay Lines to a Short Input Stimulus

Abstract

The influence of the diameter of a light beam, the duration of an input pulse, and the velocity of propagation of elastic waves on the formation of the signal at the output of an acousto-optic delay line (AODL) with direct detection is discussed. The specific features of the use of the classical method for calculating the AODL output response are considered. It is shown that the classical method can be used to calculate the output signal only when the duration of the input pulse is greater than the time constant of the AODL.
