Investigation on CO(2) laser irradiation inducing glass strip peeling for microchannel formation.

The study investigates the use of CO(2) laser to induce glass strip peeling off to form microchannels on soda lime gass substrate. The strip peeling exhibits a strong dependence on the energy deposition rate on the glass surface. In spite of the vast difference in the combination of laser power and scanning speed, when the ratio of the two makes the energy deposition rate in the range 3.
