Class Information
Number: 359/331
Name: Optical: systems and elements > Optical frequency converter > Optical laser acoustic delay line type
Description: Subject matter wherein the output from a laser is mode-locked and passed through an acoustic cell in which a radio frequency acoustic wave has been generated; the laser beam is diffracted, and one of the frequency shifted diffracted modes is heterodyned at a detector with an unshifted mode to produce a time delayed radio frequency output signal lower in frequency than the input signal.
