Description
Summary:We report an investigation of ablating several materials using a nanosecond pulse duration Nd{/content/KWV6BALA4XYWGPN7/xxlarge8201.gif}:{/content/KWV6BALA4X Y WGPN7/xxlarge8201.gif}YVO4 micro-laser operating at wavelengths of 1064 and 532 nm and high pulse-repetition rate ({/content/KWV6BALA4XYWGPN7/xxlarge8804.gif}20 kHz). Probe beam deflection, ballistic pendulum measurements and scanning electron microscopy are used to characterise the interaction. It is shown that good-quality micro-scale features can be produced in polyimide, gold foils and silicon targets by ablation using this laser.
