Abstract

The effect of vacuum level on laser induced white emission (LIWE) of graphene foam is investigated. The results are compared with the electric incandescence of tungsten wire. The increase in pressure inside the dynamic vacuum chamber reduces the emission intensity of LIWE and has no effect on the emission of the electrically driven tungsten wire. The same dependency was observed in the case of field emission (FE) of carbon cathodes. The analogy confirms that white emission and FE are coincident processes occurring during laser excitation of graphene foam.
