The authors optimized the processing parameters of laser shock peening (LSP) of stainless steel, taken as a representative metal, using a Ti:sapphire laser with pulse durations in the range of 100 fs–2 ps. It was found that direct exposure of the m

It is shown that controlled irreversible surface softening can be obtained in thermoset polymer of allyl diglycol carbonate (CR-39) without degrading its bulk properties on treating it with a cw-CO2 laser. An average value of the threshold fluence fo

To explore the possibility of extracting cataracts percutaneously, we have carried out in-vitro studies on ablation of cataractous human eye lenses using a TE-C02 laser of pulse duration 135 nsec FWHM. The threshold flue2ce of ablation is found to be
