Abstract

Excitation of cholesteric liquid crystal lasers with a large diameter pumping spot is considered. It is shown that the introduction of spatial modulation into the pump beam transfers light emission of the liquid crystal layer from the luminescence mode to the lasing mode. Furthermore, the possibility of dynamic recording of information on a laser optical layer with a thickness of 12µm and an area of about 40mm2 is demonstrated.
