Paper Abstract

Pits formation during the laser induced damage with GaAs surface either for picosecond or for femtosecond laser pulses, shows that defects always play an important role in damage morphology of GaAs surface, as previously these pits formation have also been seen for micro and nanosecond laser pulses. The nature of these pits gives an important information about the morphological features of damaged GaAs surface in picosecond and femtosecond regime. In this paper we report a comparative study of laser induced damage morphology of GaAs surface based on the nature of these pits formation.
