Laser-induced damage mechanisms were investigated for an ultra-broadband chirped mirror, as part of a systematic study of few-cycle pulse laser-induced damage threshold (LIDT) of widely-used ultra-broadband optics, in vacuum and in air, for single an

The fundamental mechanisms of tip-enhanced Raman spectroscopy (TERS) have been investigated, including the role of the plasmonic excitation of the metallic tips, the nature of the optical tip–sample coupling, and the resulting local-field enhanceme
