Anomalous Single-Mode Lasing Induced by Nonlinearity and the Non-Hermitian Skin Effect
Anomalous Single-Mode Lasing Induced by Nonlinearity and the Non-Hermitian Skin Effect
Single-mode operation is a desirable but elusive property for lasers operating at high pump powers. Typically, single-mode lasing is attainable close to threshold, but increasing the pump power gives rise to multiple lasing peaks due to inter-modal gain competition. We propose a laser with the opposite behavior: multimode lasing occurs …
