ABSTRACT:
A dual wavelength laser is disclosed for use in dental therapeutic applications. The dual wavelength laser includes a laser cavity in which a laser crystal is disposed and preferably the laser crystal is an Nd:YAG laser, which, upon excitation, lases at two different wavelengths, each of which has a different gain. A shutter, or alternatively an optical filter, is selectively disposed within the optical path of the laser crystal whereupon the higher gain wavelength is selectively suppressed. Thus, with the shutter or optical filter removed from the optical path, the laser lases at its higher gain wavelength. Conversely, with the shutter or filter positioned within the optical path, the higher gain wavelength is effectively suppressed so that the laser crystal lases at the lower gain wavelength.
