Abstract

The therapeutic laser apparatus includes at least two wands connected to a controller and radiation source via fiber optic cables. The controller and source include at least two infrared wavelength solid-state diode (“SSD”) lasers and at least two visible wavelength SSD aiming lasers. The apparatus further includes a combiner configured to maintain the electromagnetic radiation from one infrared SSD laser coincident with one visible light SSD aiming laser. In the method according to the invention, the visible light SSD aiming laser is used as a pointer so that an operator can position the wands adjacent to the skin of a mammal whereby the beams of infrared treatment lasers intersect at a region inside the body of the mammal.
