Wavelength-selective laser ablation and modification of diamond films.

摘要

his thesis reports the observation of strong wavelength-dependent photodamage in diamond films in the vicinity of the C-H stretch vibrational mode. This is an important deviation from previous ablation research which has typically centered upon the intensity and pulse duration dependencies. The Vanderbilt Free-Electron Laser (FEL), which produces intense tunable (2 to 10 ;Near the C-H stretch absorption band (3.47
