Abstract
In this report we have presented the results of forming waveguide structures in the bulk of porous glass (PG) plates soddened with water solutions of different concentrations of glycerol — substance with high polarizability under the laser irradiation of wavelength low absorbed by plate material. Chemical composition of the plate used in experiment was such: 94.73SiO2 – 4.97 B2O3 – 0.30 Na2O, with porosity δpg= 0.26 cm3/cm3 and average channel size 2÷4 nm. As the irradiation source the pulse fiber ytterbium laser with wavelength 1.07 um and with pulse duration ~100 ns and pulse frequency 10÷100 kHz was used. Waveguide structure forming was occurred while the PG plate was moving with velocity 2÷3 um/s relatively to the formed irradiation beam.
