Abstract
A laser handpiece using an optical system such as a prism. The laser handpiece includes a laser fiber for irradiating laser beam output from a laser generating device, a first beam path changing portion for changing a traveling path of the laser beam output from the laser fiber, a second beam path changing portion for changing finally the traveling path of the laser beam output from the first beam path changing portion, a focus lens for focusing the laser beam output from the second beam path changing portion onto a point, and a main body for containing the laser fiber, the first beam path changing portion, the second beam path changing portion and the focus lens. Thus, an optical axis can be easily aligned and the traveling path of the laser beam can be easily changed within a small space, so the laser handpiece can be manufactured in a convenient shape for use.
