Abstract
An electronic cigarette includes a main body and a replaceable cartridge that can be disassembled from the main body. The main body includes a laser. The cartridge includes a liquid store and an absorber configured to be heated by radiation emitted by the laser in order to vaporise a vaporisable medium. An enabling device is also provided to enable propagation of radiation from the laser to the absorber when the cartridge is assembled to the main body and to inhibit propagation of radiation from the laser to the absorber when the cartridge is disassembled from the main body.
