It is the output power and density of the lasers which determine whether a laser is a low or high-power one. If the density is less than 670mW/cm2, the laser is called a low power one. The output power of these lasers is usually less than 250mW. They use different mechanisms to accelerate wound healing such as: cellular biostimulation, improvement of circulation, vasodilation, analgesic and ant...
