Cosmetic method and apparatus for the treatment of skin tissue using two wavelengths of laser energy

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 comprising a light path, the handpiece configured to receive two laser beams generated by the two laser generating engines and treat the skin tissue;
• an adjustable beam deflector along the light path 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 handpiece to the skin tissue and impinge as laser spots onto the skin tissue at the same time but separated by a distance and non-overlapping.

A method for treating skin tissue comprising:

• providing a two-laser energy generating engines, wherein
• the two laser generating engines operate to produce laser beams, one at 1410 nm and the other at 1927 nm wavelengths;
• providing a handpiece comprising a light path for receiving the two laser beams generated by the two-laser energy generating engines, the handpiece being in operative connection with the at least two laser energy generating engines;
• providing an adjustable beam deflector along the light path of the handpiece;
• providing 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 method further comprising:
• the controller:
• (1) causing activation of both of the two laser energy generating engines at the same time and (2) causing movement of the adjustable beam deflector such that the at least two laser beams are deflected to pass through the handpiece and impinge as laser spots onto the skin tissue at the same time but separated by a distance and non-overlapping.
