The local crystallization of barium-titanosilicate glass under the action of a femtosecond laser beam is investigated. The effect of the laser beam scanning speed and laser pulse energy on the morphology of channels containing Ba 2 TiSi 2 O 8 fresnoite crystals is determined. The preferential orientation of fresnoite crystals in the formed channels has been established by the method of polarization Raman spectroscopy. The results obtained open up prospects for the development and manufacture of waveguide crystal structures with low optical losses for photonics and integrated optics.
