This study presents the comparison of laser drilling of nickel based superalloy in air and vacuum environment. A 300W Nd:YAG laser was used to carry out the experimental study, pulse width and pulse peak power were studied of their influence on the hole quality and appearance, the experiments were respectively conducted in air and vacuum. It was found that the holes drilled in vacuum were much different to those drilled in air. Laser of shorter pulse width may drill the better holes in the air, but in the vacuum it was the pulse width around 1ms that produced holes of the best quality.
