Abstract :
In this paper the etching and structuring of zinc oxide, indium tin oxide by ultrashort laser pulses is analysed. A Ti:sapphire laser, which provides 120 fs pulses at a wavelength of 775 nm, was used to etch the samples at room temperature in air as well as in vacuum. The surface topography of the etched semiconductors has been investigated.
