1. A laser device comprising:
- a) a plurality of laser energy sources for generating a plurality of laser beams;
b) a wand from which the laser beams emit, the wand housing the laser energy sources within and being capable of being retained in a hand of a user and freely moved relative to the surface of the skin of a patient; and
c) an optical arrangement attached to the wand for receiving the laser beams and for transforming each of the laser beams into a desired spot shape.

Abstract
An improved hand-held laser device that can simultaneously provide multiple types of low level laser therapy treatments. The device enables laser light of different pulse widths, different beam shapes and spot sizes to be applied externally to a patient'"'"'s body. The device includes multiple laser sources. In the preferred embodiment, two semiconductor diode laser sources simultaneously provide two separate laser beams, one laser beam producing a line of continuous red laser light and the other producing a spot of pulsed laser light.

13. A therapeutic laser device comprising:
-
a) a first semiconductor diode laser energy source generating a first laser beam having a first pulse width and a second semiconductor diode laser energy source generating a second laser beam having a second pulse width, wherein at least one of the laser beams has a wavelength in the red range of the visible spectrum;
b) a wand from which the laser beams emit, the wand having an interior cavity that houses the laser energy sources and that is capable of being retained in a hand of a user and freely moved relative to the surface of the skin of a patient;
c) an optical arrangement mounted in the interior cavity of the wand for receiving the laser beams and for transforming each of the laser beams into a desired spot shape wherein the first laser beam'"'"'s spot shape is substantially linear and the second laser beam'"'"'s spot shape is substantially circular;
d) a control circuit for controlling the first pulse width and the second pulse width wherein the first pulse width is a continuous emission and the pulse width is greater than zero.
