1. An atomiser for an electronic cigarette, comprising:
a housing including at least one air inlet, at least one air outlet and a liquid inlet;
a light guide extending into the housing;
an optical absorber within the housing; and
a vaporisation chamber within the housing, wherein a liquid flow path is provided from the liquid inlet towards the optical absorber and the vaporisation chamber, and an air flow path is defined from the at least one air inlet in the housing to the vaporization chamber, and wherein the light guide is configured to couple light from a vaporising light source towards the optical absorber which can generate heat by absorbing light from the vaporising light source,
wherein the optical absorber includes a liquid absorber for absorbing vaporisable liquid received in the liquid inlet, and
wherein the optical absorber is provided within the vaporization chamber axially above an end face of the light guide with respect to an axial direction of the housing.
