Effect of Laser Action on the Exoelectron Emission from the Surface of Metals,
Abstract
The effect of laser action on the surface of pure Au, Pt, Pd, Ni, and of alloys 1Kh18N9T and 40N25 was studied by the exoelectron emission method described previously (Kortev, et al., 1966). No emission was observed at room temperature. At higher temperatures thermoemission passed through a maximum Pt and Pd exhibited 2 peaks at different temperatures. Emission was due to laser action. Cracks and changes in relief and stresses occurred on the surface. The peaks of deformed specimens exposed to air decreased. This might be due to relaxation of stresses as well as to the deactivation of structural defects on the surface. (Author)
