摘要
We report on the elemental redistribution behavior in oxyfluoride glasses with a high repetition rate nearinfrared femtosecond laser.Elemental analysis by an electro-probe microanalyzer demonstrates that the redistributions of Ca^2+and Yb^3+ions change dramatically with pulse energy,which are quite different compared with previous reported results.Confocal fluorescence spectra of Yb^3+ions demonstrate that the luminescence intensity changes obviously with the elemental redistribution.The mechanism of the observed phenomenon is discussed.This observation may have potential applications in the fabrication of micro-optical devices.
