Abstract

For the first time, studies on stimulated Brillouin scattering (SBS) pulse compression based hundred picoseconds laser processing of Cu, Mo, W and Ti have been experimentally investigated. Different from other laser output, the pulse width of the SBS pulse compressed laser is about 450 ps with a steep rising edge. The number of pulses to drill through the four kinds of metals with thicknesses 1 mm have been measured. The diameters, depths and morphologies of the drilled craters were observed with optical microscope and scanning electron microscope (SEM). Different micro structures on the four metals are obtained in our experiment. Our research provides a potential application of high energy hundred picoseconds lasers in the future.
