FIG. 1.

(Color online) White light images of lines written with the megahertz system using a pulse energy of and scanning the sample transversely at (a) and (b) . The circular fringes are artifacts from the microscope. Dashed lines indicate the approximate boundary of the waveguides.

FIG. 2.

(Color online) Sample spectrum of a waveguide written with the megahertz laser system using a laser pulse energy of and scanning the sample transversely at .

Image of FIG. 3.
FIG. 3.

(Color online) (a) Normalized Raman peak ratios and (b) fluorescence intensities for lines written using a repetition rate laser system at different scan speeds and pulse energies. The data is normalized with respect to the unmodified glass.

Image of FIG. 4.
FIG. 4.

(Color online) (a) Raman peak ratio and (b) fluorescence intensity spatial profile for waveguides written with a laser and a pulse energy. Both plots are normalized to the data for unmodified glass.
