1. A laser treatment device for treating skin tissue comprising:
two laser energy generating engines;
the two laser generating engines operating to produce laser beams, one at 1410 nm and the other at 1927 nm wavelengths;
a handpiece for receiving the two laser beams generated by the two laser energy generating engines, the handpiece being in operative connection with the two laser energy generating engines;
the handpiece including a proximal end and a distal tip, further comprising one or more mirrors along a light path to receive each of the two laser beams from the proximal end and to convey the two laser beams to the tip of the handpiece;
the handpiece further comprises one or more passageways along the light path from the proximal end to the distal end of the handpiece to carry air from an external source to the distal end of the handpiece and then the skin tissue;
an adjustable beam deflector along the light path between the distal and the proximal end of the handpiece;
a controller in the laser treatment device to control the activation of the two laser energy generating engines and control movement of the adjustable beam deflector;
the controller being configured to: (1) cause activation of both of the two laser energy generating engines at the same time and (2) cause the movement of the adjustable beam deflector such that the two laser beams are deflected to pass through the distal tip of the handpiece and impinge as laser spots onto the skin tissue at the same time but separated by a distance and non-overlapping.
