Loss-induced suppression and revival of lasing
B. Peng, S. K. Ozdemir, S. Rotter +6
Controlling and reversing the effects of loss are major challenges in optical systems. For lasers losses need to be overcome by a sufficient amount of gain to reach the lasing thre…
Mid-infrared laser filaments in the atmosphere
A. V. Mitrofanov, A. A. Voronin, D. A. Sidorov-Biryukov +8
Filamentation of ultrashort laser pulses in the atmosphere offers unique opportunities for long-range transmission of high-power laser radiation and standoff detection. With the cr…
Invariance property of wave scattering through disordered media
Romain Pierrat, Philipp Ambichl, Sylvain Gigan +3
A fundamental insight in the theory of diffusive random walks is that the mean length of trajectories traversing a finite open system is independent of the details of the diffusion…
Atomic scale electron vortices for nanoresearch
J. Verbeeck, P. Schattschneider, S. Lazar +4
Electron vortex beams were only recently discovered and their potential as a probe for magnetism in materials was shown. Here we demonstrate a new method to produce electron vortex…
Reversing the Pump-Dependence of a Laser at an Exceptional Point
M. Brandstetter, M. Liertzer, C. Deutsch +6
When two resonant modes in a system with gain or loss coalesce in both their resonance position and their width, a so-called "Exceptional Point" occurs which acts as a source of no…
