One, the hydrodynamic effect: mainly produce high power laser excitation water molecules of fluid mechanics.
Water molecules can easily absorb the wavelength of laser energy, but not destroy the bonding structure of water molecules.
If the laser energy, hit the water molecules can make water molecules inspire with high-speed kinetic energy of the state, the sound effect of fluid kinetic energy can achieve organization cutting, the cutting the organization of a water molecule is used as the medium.
2, temperature effect: soft tissue cutting mainly to achieve this effect. Tissue temperature rises after absorption of laser energy, when the temperature 370 c - 600 c organization does not produce change, once more than 600 c would solidifies, to the effect of hemostasis, when the temperature exceeds 1000 c, cell moisture will evaporate, dehydration of tissue left more than 2000 c will be carbonized.
3, mechanical effect of laser cutting machine hard tissue ability comes not from temperature effect, but will be organized by energy increased pressure caused by water evaporation of the organization, in hard tissue melting point not cause tissue rupture, long before the arrival of this phenomenon, called micro explosion, and no directly related to the temperature effect.
