The etching of ceramic PbTi1−xZrxO3 (PZT) by XeCl excimer laser radiation has been investigated. In air, the threshold fluence for etching was about 2 J/cm2. At fluences of 10 J/cm2, etch rates of 0.1 μm/pulse were observed. The geometry of etched structures can readily be defined by choosing suitable experimental conditions, suggesting potential applications of this process to the production of devices.

The laser-induced etching of ceramic PbTi1−xZrxO3 in a hydrogen atmosphere and in air has been investigated. Visible Ar+ and Kr+ laser radiation was employed in most of the experiments. In H2 atmosphere, regular patterning of the ceramic is possible. Average etch rates reach up to about 250 μm/s.
