Abstract

Lasers are flexible tools which have proven their reliability in machining materials for many years already. This paper studies the effect of Nd:YAG laser machining on a photographic paper at atmospheric pressure. The laser has a wavelength of 1064 nm and pulse duration of 8 ns. A single lens technique was used to focus the laser beam on the photographic paper. The focused laser beam can generate up to tens of GW/cm2 of peak intensity on the photographic paper, thus producing an asymmetrical shapes of machining area on its surface. A photomicroscope in conjunction with image processing system were used to store and analyze the machined area. The measurement of the machined area is based on its size. The results show that the minimum and maximum machined diameter are 290 L i m and 436 u.m at peak power of 21.61 MW and 21.93 MW respectively.
