Abstract
A non-contact laser handpiece contains optical components modified to provide a high-density uniform laser beam at a distance from the handpiece that minimizes effects of back reflection.
Claims20
A handpiece for laser treating a tissue target surface, comprising:
- a window coupled to receive and output electromagnetic energy;
- a reflector aligned to redirect electromagnetic energy outputted from the window;
- and
- a tip positioned to receive electromagnetic energy from the reflector and shaped to generate an output of electromagnetic energy that converges at a selected distance from an emitting surface of the tip.

A non-contact handpiece for laser tissue cutting, comprising:
- a window adapted to receive electromagnetic energy from a waveguide;
- a reflector that is capable of redirecting electromagnetic energy received from the window;
- and
- a tip that can receive electromagnetic energy from the reflector and direct it from an emitting surface thereof to converge at a selected and controlled distance, the electromagnetic energy at the selected distance having a cross-sectional area that is less than a cross-sectional area of the electromagnetic energy at the emitting surface.

A laser handpiece for tissue cutting, comprising:
- a waveguide disposed to receive electromagnetic energy from a laser source;
- a window coupled to receive electromagnetic energy from the waveguide;
- and
- a reflector aligned to receive electromagnetic energy from the window and redirect the electromagnetic energy to an output tip;
- wherein the output tip comprises an emitting surface that converges electromagnetic energy received from the reflector to focus at a selected and controlled distance.
