    Raman studies of micro-machine glasses with variable repetition rates, at GOMD Fall Meeting 2004 (Cocoa beach, FL), Tuesday, November 9, 2004:
    Structural changes in borosilicate and fused silica glasses modified by a femtosecond laser at different laser repetition rates were investigated. The sample was submitted to femtosecond laser pulses at a rate ranging from 1 kHz to 25 MHz in the regime where the sample could experience from a rapid cooling to a cumulative heating respectively. Changes in the glass networks of the modified region were recorded via Raman microscopy using an Ar laser at 514 nm as an excitation. Due to fluorescence background in fused silica, relative peak intensities at 605 cm-1 800 cm-1 were observed for...
