Abstract
The ablation of porcine skin tissue has been investigated using nanosecond (ns) laser pulses at the wavelengths of 1064, 532 and 266 nm. The ablation probability has been measured near the threshold through detection of the secondary radiation from the tissue sample surface at different wavelengths. Experimental results have indicated that the ablation of the skin tissue in the wide range of ablating wavelength is caused by optical breakdown induced by the strong electromagnetic field of the nanosecond pulses. Furthermore, we conclude that the initial seed electrons acquire ionization energy from the incident optical field mainly through a momentum-relaxing drift mechanism.
