A simple model for flyer velocity from laser-induced forward transfer with a dynamic release layer

► First model for LIFT flyer velocity, based on explosive Gurney energy model. ► Model takes into account laser beam and decomposition energies as inputs and assumes all deposited laser energy above a threshold is used as kinetic energy of decomposition products and the flyer. ► Experimental flyer velocities obtained by shadowgraphy of aluminium flyers in vacuum. ► Model velocities fit experimental velocities well just by adjusting reflective losses of laser beam energy.
