NANOPULSED ABLATION RATE OF METALS DEPENDENCE ON THE LASER FLUENCE AND WAVELENGTH IN ATMOSPHERIC AIR

The dependence of ablation rate of aluminum, titanium and copper on the nanosecond laser fluence with 532 nm and respectively 1064 nm wavelengths is investigated in atmospheric air. The wavelength is varied by using the fundamental and second harmonic of a Q-switched Nd-YAG laser system and the flue...

Zusammenfassung:The dependence of ablation rate of aluminum, titanium and copper on the nanosecond laser fluence with 532 nm and respectively 1064 nm wavelengths is investigated in atmospheric air. The wavelength is varied by using the fundamental and second harmonic of a Q-switched Nd-YAG laser system and the fluence of the pulses is varied by changing the diameter of the irradiated area at the surface target. The results indicate an approximately logarithmic increase of the ablation rate with the fluence for both irradiation regime and a higher efficiency of the ablation in the case of 532 nm pulses.
