Abstract

We describe a study of single/few pulse machining of glass with 150fs pulses at 800nm (Ti:sapphire) and present results demonstrating in a quantitative way the dependence of the machining quality on the focal position and the pulse energy of the laser beam. We report experimental results on how sub-diffraction limited structures can be created. A theoretical calculation of the ablation threshold of glass is made from our experimental results, found to be 5.55J/cm². Results are also presented that illustrate the dependence of the machining quality on the pulse length used. A technique for optimising the focal position at energies below the machining threshold is detailed and we will also present results of a related study investigating the self focusing of femtosecond beams in air.
