Abstract

The surface morphology of HgCdTe wafer irradiated by a single pulse from a Nd:YAG laser (wavelength 0.53 micrometers , pulse width 10 ns) is studied in this paper. The surface structures are related to surface acoustic standing waves, bulk acoustic waves, Hg atoms depletion and boiling of melting surface layer. A plot of damage site area versus pulse laser energy density have been given.
