The structure modification in the bulk of plates of photochromic porous glass (PCPG) containing 0.28 wt % Ag2O under the action of laser irradiation of a near IR-range with a power density of 0.6–1.9 MW/cm2 and irradiation duration of 5–20 s is carried out. Locally modified structure regions are composed of the central and edge parts with a different content of silver nanoclusters and different density...
An attempt at local modification of the optical properties in the interior of macroporous glass plates with porosity 0.58 cm3/cm3 and average channel size 50 – 70 nm by means of laser radiation weakly absorbed in the material is reported. The source of radiation is an ytterbium fiber laser with radiation wavelength λ = 1.07 μm, pulse duration τp ~ 100 nsec and pulse repetition frequency ν = 10 – 100...
