Mechanism and effects of surface morphology on absorption characteristics in ultrashort pulse laser processing of sapphire
For ultrashort pulse laser processing of a sapphire wafer, nonlinear absorption of laser energy at sufficiently high laser intensity is essential. This study found that in ultrashort pulse laser processing of a sapphire wafer, its surface morphology can have a significant effect on nonlinear absorpt...
