Abstract
A stand-alone laser device that provides low level laser therapy using one or more laser sources. The laser sources are attached to one or more arms which can be positioned to cause the laser light to impinge on a desired area of a patient's body. A scanning apparatus is attached to the arms which comprise structures that cooperate to cause an optical element to be able to simultaneously rotate about a central axis and move in a linear motion along that axis to achieve any desired scan pattern. Laser light of different pulse widths, different beam shapes and different scan patterns can be applied externally to a patient's body. In the preferred embodiment, red light having a wavelength of about 635 nm is used to stimulate hair growth on a patient's scalp.
