We report on the laser-assisted deposition of metals by pyrolytic and photolytic dissociation of metal alkyls. A Kr+ laser is used to pyrolytically deposit Al, Cd, and Zn on optically absorbing substrates; deposition rates are typically a few um/s. A frequency-doubled Ar+ laser is used to deposit Ga by photolytic decomposition of the parent molecules on quartz substrates. Cadmium deposition is achieved by photolysis of the parent molecules adsorbed on the quartz substrate using the visible output of a Kr+ laser. The time evolution of these processes is studied by measuring in situ the optical transmission during deposition. We have observed different morphologies which depend on the deposition mechanism.
