NEW PROGRESS IN THE INVESTIGATION OF PULSED LASER-INDUCED FAILURE MECHANISM

This paper reveals a new kind of pulsed laser-induced failure mode,which wasexperimentally observed in thin target plate of brass and was named as reverse plugging effect (RPE)by the authors previously.In the test,a pulsed Nd:Glaiss laser beam is used withduration 0.3ms,total energy 30-40J, spot size 2-5mm and particuldrily with a spdtialshape of non-Gaussian type,Theoretical analyses are presented for this newly-observed phenomenon,The present investigation confirms that the laser-induced failurfe mode c...
