Paper Abstract

Laser solid interaction with < 100 fs pulses from 800 - 3600 nm wavelength was studied at 45 degree angle of incidence with s- and p-polarized light. Mid-IR femtosecond laser damage thresholds of Si, Ge, and ZnSe were determined. Obtained results were compared against existing Two Temperature Model for laser damage which was shown to fail at longer wavelengths. Experimental evidence suggests that electron dynamics at the interaction vacuum-solid interface contribute to lowering of laser damage threshold at longer wavelengths.
