Abstract

We report greatly enhanced femtosecond laser-induced precipitation of nonlinear optical crystals in glasses owing to the addition of silver. Ba 2 TiSi 2 O 8 (BTS) crystals were space-selectively precipitated inside a Ag + -doped BaO TiO 2 SiO 2 glass by using a focused femtosecond laser with 800 nm, 250 kHz, and 150 fs. The laser induced crystals were confirmed by micro-Raman spectra to be BTS phases. The irradiation time for crystallization in Ag + -doped BaO TiO 2 SiO 2 glasses was much shorter than that in undoped BaO TiO 2 SiO 2 glasses under the same irradiation conditions. The mechanism responsible for the observed phenomenon is discussed.
