Exceptional points as lasing pre-thresholds in open-cavity lasers
A. A. Zyablovsky, I. V. Doronin, E. S. Andrianov +4
The genesis of lasing, as an evolution of the laser hybrid eigenstates comprised of electromagnetic modes and atomic polarization, is considered. It is shown that the start of cohe…
Self-formation of coherent emission in a cavity-free system
A. A. Zyablovsky, I. V. Doronin, E. S. Andrianov +4
It is commonly accepted that a collection of pumped atoms without a resonator, which provides feedback, cannot lase. We show that intermodal coupling via active atoms pulls the fre…
Photon statistics of amplified spontaneous emission
I. V. Doronin, E. S. Andrianov, A. A. Zyablovsky +4
Developments in quantum technologies lead to new applications that require radiation sources with specific photon statistics. A widely used Poissonian statistics are easily produce…
Inversion of a two-level atom by quantum superoscillations
I. V. Doronin, A. A. Pukhov, E. S. Andrianov +2
We show that a two-level atom with a high transition frequency ω_SO can be inverted via non-radiative interaction with a cluster of excited low-frequency two-level atoms or quantum…
