Abstract

This paper first reports random laser action in dye-doped ferromagnetic nematic liquid crystals, which act as a randomly distributed cavity. The random laser intensity of the ferromagnetic nematic liquid crystals can be controlled by a weak magnetic field (∼1 mT). Moreover, the magnetic switching of random laser is attributed to the direction and polarization dependent emission of light in the ferromagnetic nematic liquid crystals in an external magnetic field.

摘要

本文首次报道了染料掺杂的铁磁向列型液晶中的随机激光行为，其作为随机分布的腔。铁磁向列型液晶的随机激光强度可由弱磁场（约1毫特斯拉）控制。此外，随机激光的磁开关归因于外部磁场中铁磁向列型液晶中与方向和偏振相关的光发射。
