Laser-induced forward transfer of carbon and chromium films in gases of one atmosphere pressure

Abstract

The report shows for the first time that LIFT can produce patterned spots of desired thicknesses, and we also compare ambient gas of air versus helium at one atmosphere pressure. We utilize a focussed pulsed laser beam of high repetition rate to produce localized transfer from the emitting film to the collecting surface with high spatial resolution. The adjustment of the spot thickness is achieved by translating the emitting film after each laser pulse while keeping the irradiation spot and the collecting surface stationary.
