Abstract: It is shown that pulsed irradiation (a wavelength of 10.6 μm and an energy density of 0.6–8.5 Jcm^-2) of glass with a waveguide layer containing silver ion leads to the formation of a ring, surrounding the irradiated zone and consisting of silver nanoparticles deposited on the glass surface. The possible process of formation of silver nanoparticles under laser irradiation is discussed.

Keywords: evaporation, CO₂ laser, glass, silver nanoparticle.
