<title>Wide band-gap materials microprocessing by femtosecond laser pulses</title>

Abstract

The experimental results of wide band-gap materials treatment by femtosecond laser pulses are presented and discussed. Borosilicate glass drilling in air and vacuum, the surface and in-bulk three-dimensional laser processing with sub-micrometer resolution are subject of investigatios. Technical issues relevant for achieving high spatial resolution in order to meet requirements of nanotechnology at feature size smaller than 10 nm along with the issues of fabrication efficiency are outlined. Also, we show a concept of modular laser processing system, which can be flexibly optimized for processing by femtosecond laser pulses.
