Output beam shaping of a multimode fiber amplifier
Stefan Rothe, Kabish Wisal, Chun-Wei Chen +4
Multimode fibers provide a promising platform for realizing high-power laser amplifiers with suppressed nonlinearities and instabilities. The potential degradation of optical beam…
Optimal input excitations for suppressing nonlinear instabilities in multimode fibers
Kabish Wisal, Chun-Wei Chen, Zeyu Kuang +3
Wavefront shaping has become a powerful tool for manipulating light propagation in various complex media undergoing linear scattering. Controlling nonlinear optical interactions wi…
Exploiting spacetime symmetry in dissipative nonlinear multimode amplifiers for output control
Chun-Wei Chen, Kabish Wisal, Mathias Fink +2
Time-reversal symmetry enables shaping input waves to control output waves in many linear and nonlinear systems; however energy dissipation violates such symmetry. We consider a sa…
