Abstract

We report the first experiments showing structural changes in borosilicate glass using just a short-cavity Ti:sapphire oscillator at 800 nm and 90 MHz. Micromachining is achieved with infrared femtosecond pulses having record-low energies. We show 3-D patterning capability, including waveguides and 3-D gratings embedded in the volume of a glass slab.
