Abstract

Femtosecond laser pulses are ideal for many precise and delicate laser processing applications. In this work, we demonstrate that femtosecond laser pulses can be used to produce microscopic holes (< 100)mum diameter) with macroscopic depth (>1 mm) in silicate glasses at atmospheric pressures. These experiments indicate that self-focusing is an important factor affecting hole depth at high laser intensity. (C) 2001 Elsevier Science B.V All rights reserved.
