In this Letter, we theoretically analyze cavity beam propagation in a gain medium and cavity using the rate equation and generalized Huygens integral, respectively. Spontaneous chaos and extreme events (EEs) occurred around the transverse-mode-degene

Considering the birefringence of the gain medium, we propose a selection rule for designing cavity configurations that enable the generation of radially and azimuthally polarized laser beams with a low beam quality factor, i.e., high beam quality. Us

This paper demonstrated the suppression of chaos in an Nd:YVO4 laser by reshaping the pump modulation with dual waveforms. When the first sinusoidal modulation induced chaos, the second modulated signal reshaped the modulated profile to suppress the

We theoretically explore the phase transition in inhomogeneous exciton-polariton condensates with variable pumping conditions. Through Bogoliubov excitations to the radial-symmetric solutions of complex Gross-Pitaevskii equation, we determine not onl

A period-doubling route to chaos was observed in a passively Q-switched Nd:GdVO4 laser beam with azimuthal polarization. At a period of two, the peak intensities gradually varied with the azimuthal angle. When the pump power was increased, the chaoti

This study numerically investigates the nonlinear dynamics and the changes of the threshold of chaotic behavior in a pump-modulation Nd:YVO 4 laser using the single-humped and doubled-humped modulation profiles. The nonlinear dynamics mainly follows
