Periodically loss-modulated CO sub(2) laser as an optical amplitude and phase multitrigger

For the hard mode excitation of the nonlinear dynamics system, an additional optically controlled impulsive perturbation of cavity losses formed due to absorption on nonequilibrium charge carriers in the semiconductor elements of a CO sub(2) laser was proposed. The operation of a modulated CO sub(2) laser as a double or quadratic phase trigger as well as an amplitude optical trigger was demonstrated. This method is quite useful for diagnosing phase space in experimental studies of nonlinear dynamics in lasers. It was noted that a radial profile of optically controllable short-lived losses can readily be contoured in space.
