Laser-Initiated Ga-Deposition on Quartz Substrates

  • Y. Rytz-Froidevaux (a1), R.P. Salathe (a1) and H.H. Gilgen (a1)


The deposition of Ga on quartz substrates by photodissociation of trimethylgallium has been investigated. Light from a frequency doubled Ar-ion laser beam (257.2 nm) was focused onto quartz substrates. The Ar-ion laser was operated under cw or mode-locking conditions. The deposition rate has been investigated as a function of averaged UV power densities in the range of 1.8 – 1750 w/cm2 and is shown to depend critically on the laser operating mode. For cw operation, the maximum growth rate within the focal zone is limited to 17 Å/s whereas under mode-locking conditions, no saturation is observed and the growth rate increases linearly with the laser power up to 70 Å/s at 1.75 kW/cm2.
