The role of electric field polarization of the incident laser beam in the short pulse damage mechanism of pulse compression gratings
Abstract : We investigate the short pulse laser induced damage initiation mechanism on multilayer dielectric
pulse compression gratings. We report that damages initiate at the edge of the grating pillars
opposite to the incoming wave. It demonstrates, at a nanometer scale, the role of the electric field
in the damage process coupled with periodic ripple pattern developing along the polarization
direction. We avoid the formation of ripples by illuminating the diffraction grating in TM
polarization and measure a significantly improved laser induced damage threshold associated with
a strong decrease of the electric field in the grating structure
