Description
We present cross-sectional transmission electron microscopy studies of laser induced periodic surface structures (LIPSS) formed on gallium phosphide after irradiation with ultrashort laser pulses with a pulse duration of 150 fs and centered at a wavelength of 800 nm. LIPSS with spatial periods (∼165 nm) substantially smaller than the incident wavelength are found to have vertical profiles as high as ∼960 nm measured from the crest to the trough. The present observations provide important insights into the formation mechanisms of subwavelength LIPSS
