چکیده
|
In this work the characteristics of nanosecond laser ablation of bulk cu is reported. bulk cu is irradiated by aq-switched nd:yag laser at 1064 nm wavelength in atmospheric air in single pulse and sweep mode. the temperatureof the plasma, formed on cu surface during the experiment is calculated from the spectroscopy measurement byrelative intensity line method. formation of copper oxide and changes in topology of the target surface are discussedin details using metallographic and sem images. the hole drilled by laser pulse on the cu surface is scanned. it isfound out that the dept of the hole is independent of temperature and is affected by the laser peak power
