A nonlinear dynamics of stimulated phonon emission in a nonautonomous acoustic quantum generator under superlow-frequency-modulated pumping conditions

Abstract: An unusual nonlinear resonance was experimentally observed in a ruby phonon laser (phaser) operating at 9 GHz with an electromagnetic pumping at 23 GHz. The resonance is manifested by very slow cooperative self-detunings in the microwave spectra of stimulated phonon emission when pumping is modulated at a superlow frequency (less than 10 Hz). During the self-detuning cycle new and new narrow phonon modes are sequentially "fired" on one side of the spectrum and approximately the same number of modes are "exting… Show more

“…The ideas of quantum electronics have also deeply penetrated into adjacent branches of modern physics, especially into quantum acoustics [4][5][6][7][8][9][10][11][12][13]. A series of new nonlinear phenomena, which arise under the quantum amplification or generation of tera-, hyper-or ultrasonic oscillations in nonequilibrium (inverted) acoustic and nanomechanical dissipative systems of various origins, have been predicted theoretically and discovered experimentally during last years [14][15][16][17][18][19][20]. The researches concerning the conditions, under which the formation of inverted states and the purposeful control over nonlinear processes in such systems (the acoustic analogs of lasers) become possible, are of significant independent interest.…”

“…As has already been emphasized in works [14,15,21,22], if one confines the consideration to the quantum amplification and generation of hypersound, i.e. the acoustic waves within the microwave range of frequencies, the following circumstances invoke the greatest interest.…”
