A vaporizer has a housing containing a power source. A laser assembly containing a laser module, such as a laser diode, is electrically coupled to the power source. A laser intensifier thermal transfer module contains a heating plate and is attached to the laser assembly. A cartridge assembly includes an inhalant supply cartridge containing inhalant, such as liquid or concentrate. The inhalant is in contact with the heating plate by way of a wick that draws the inhalant out of the supply cartridge. The laser assembly is receives electric current from the power source to activate the laser module causing the laser module to emit a beam directed toward the heating plate. The heating plate focuses the beam and generates heat sufficient to vaporize the inhalant. The inhalant is drawn through an air passageway in the cartridge for inhalation by the user.
