Paper Abstract

Through use of an acousto-optic modulator in a feedbackicircuit having an instability and a short carrier round trip time, an optical oscillator has been constructed. The frequency and character of this oscillation is very sensitively dependent on the position of the detector for the 1st order diffraction, as well as on amplifier balance, and on the total cavity round trip time. Under certain conditions the termination and reinstatement of the oscillation (with its modulation) are initiated by the slightest perturbations of the diffracted laser beam. By continuous monitoring of the signal which energizes the acousto-optic modulator and the oscillatory signal of the first order diffraction, the use of the X/Y mode on a digital oscilloscope provides the instantaneous output vs input data fc2r this instability. These data agree in detail with the complex theoretical predictions of previous work.
