Paper 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.
