Computational profiling of laser processing glass substrate for microchannel fabrication

Investigation of computational profiling of laser processing on glass substrate was carried out to provide numerical solutions to the selection of the laser parameters for microchannel fabrication. Polynomial equations were derived from DadtFit programming to classify and map the randomly scattered paired-data into four different regions, which indicated the four different phenomena induced in laser irradiation process. High order polynomial degree would robustly profile the varied laser parameter settings for glass strip peeling and thus precisely predict the channel fabrication. A high order polynomial approximation in power of 5 and a mathematical model of Taylor Series Expansion were used to profile the specific regions in the laser processing and to guide the selection of laser parameters for microchannel fabrication with high order of accuracy.
