Contamination at surfaces and interfaces is known to cause lowered damage threshold in high power laser optical components; therefore, it is important to be able to identify and measure the amount of adsorbed species. A technique has been developed f

In this time and wavelength regime optical coatings typically fail from thermal damage. Unlike catastrophic damage resulting from dielectric breakdown, one finds disparity among the thresholds for one or more of the following damage characteristics:

An experimental study has been made of electrons in the energy range 40–80 eV, inelastically scattered and diffracted from a clean Al(111) surface. The surface is prepared by epitaxial vapor deposition on a Si(111) single-crystal surface in ultrahi

Combined inelastic scattering and diffraction (inelastic diffraction) provide a means of observing low-energy electrons which have produced electronic excitation in bulk single crystals. In principle, the energy-versus-momentum dispersion of the exci

Infrared laser induced desorption (LID) has been demonstrated for water and other contaminants on nominally transparent substrates. For the samples measured to date, the LID is defect dominated for both small (120 μm) and large (380 μm) spot sizes.

Laser‐induced desorption has been demonstrated for strongly optically absorbing molecules on nominally transparent substrates. Both H2O and hydrocarbon contaminants were desorbed using a pulsed HF/DF laser source at 2.8 and 3.7 μm. Following laser
