The light absorption can cause three different types of biological effects in the skin: photomechanical, photothermal and photochemical. The photomechanical effect occurs when very short laser pulses, nanoseconds for the Q-switched [quality-switched] laser or picoseconds for the picosecond laser, produce very strong energies; in this way the tissue undergoes rapid thermal expansion, and an optical breakdown with intense shockwaves.
