Ablation of healthy human enamel is demonstrated using a 8 ns pulses at wavelength of 1064 nm and 10Hz repetition rate from a Q -switched Nd:YAG laser. The ablation result shows that an enhanced structuring quality in comparison with non- Q -switched pulse exposure. The material removal remains loca...
