We have studied the effects of superpulse YAG laser by changing its peak energy and wave length when irradiated on an animal tissue, with the idea that by changing the peak energy and pulse duration the superpulse laser could be used both for cutting and for coagulation. With the irradiation of superpulse YAG laser of three different wave lengths (1064, 532, 355 nm), it was shown that the higher the peak energy and the shorter the wave length, the better the vaporization and the lesser the thermal effect of the tissue. This laser may be used for variety of conditions.
