Unidirectional reflection lasing based on destructive interference and Bragg scattering modulation in defective atomic lattice
Xinfu Zheng, Chen Peng, Duanfu Chen +5
The novel and ingenious scheme we propose for achieving unidirectional reflection lasing (URL) involves integrating a one-dimensional (1D) defective atomic lattice with a coherent…

Unidirectional spectral singularity lasing in a defective atomic lattice
Chen Peng, Xinfu Zheng, Duanfu Chen +4
We propose an efficient scheme for achieving mode-tunable unidirectional reflection lasing (URL) by establishing a coherent gain atomic system to amplify the probe field and ingeni…

Unidirectional lasing via vacuum induced coherent in defective atomic lattice
Xinfu Zheng, Chen Peng, Duanfu Chen +5
We skillfully utilized vacuum induced coherence to amplify the probe light, and then successfully achieved both nonreciprocal reflection and lasing oscillation in a single physical…
