Controlling multi-wave mixing signals via photonic band gap of electromagnetically induced absorption grating in atomic media
Yiqi Zhang, Zhenkun Wu, Xin Yao +4
We experimentally demonstrate dressed multi-wave mixing (MWM) and the reflection of the probe beam due to electromagnetically induced absorption (EIA) grating can coexist in a five…
Fresnel diffraction patterns as accelerating beams
Yiqi Zhang, Milivoj R. Belić, Huaibin Zheng +4
We demonstrate that beams originating from Fresnel diffraction patterns are self-accelerating in free space. In addition to accelerating and self-healing, they also exhibit parabol…
Multicharged optical vortices induced in a dissipative atomic vapor system
Yiqi Zhang, Milivoj R. Belic, Zhenkun Wu +4
We investigate numerically the dynamics of optical vortex beams carrying different topological charges, launched in a dissipative three level ladder type nonlinear atomic vapor. We…
