Biological Effects of Laser

● Thermal effect: the irradiated tissue can elevate temperature, correct optical output port temperature is even a few hundred or thousands of degrees, use the organization to make the water boiling, increase pressure, and separate organization. At the same time, make the edge to have a coagulation or vaporization, so you can get a cutting, freezing, evaporation and other clinical results.

● Photochemical effect: biological macromolecules absorb the laser photon energy and cause chemical reactions in vivo series, it can reduced the activity of enzymes, amino acids, proteins, nucleic acids, or have an effect on treatment and diagnosis.

● EMF effect: in the form of electromagnetic fields play a role in biological tissue.

● Pressure effect: radiation pressure, air recoil pressure, pressure within the gasification, thermally induced expansion of pressure, electrostrictive pressure and so on.

● Stimulating effect: mainly in the weak laser, biology absorb photons, get energy, change and have biological reaction.
