Abstract [en]

Digital, defocused speckle photography was used for the in-situ, real-time determination of the strain field round the focus spot of a pulsed Nd:YAG laser. These surface strains can cause cracking during laser cutting and drilling of advanced engineering ceramic materials. A CW HeNe laser was used for illumination, images being captured by CCD camera with a 633 nm band pass filter, synchronised to operate between the individual laser pulses. Targets included alumina and stainless steel.
