Abstract
An electronic cigarette includes a laser and a replaceable atomiser. A reservoir is provided for storing a vaporisable liquid. The replaceable atomiser includes a light guide, an absorber and a vaporisation chamber. A liquid inlet in the atomiser provides a flow path for liquid in the reservoir to flow towards the absorber and the vaporisation chamber. The light guide is configured to couple light from the laser towards the absorber which can generate heat by absorbing the emitted light and this can cause vaporisation of the vaporisable liquid. When the light guide becomes dirty or contaminated it can be replaced simply by replacing the atomiser.
