A mains electricity (AC-powered) device assembly in which input energy (e.g., flashlamp, diode laser) is used to excite a glass/crystal rod to emit a high-power laser beam intended for application in dental procedures; it does not include frequency-doubling technology. It typically includes a light source, delivery/positioning device(s), controls/foot-switch. It is intended to incise, excise, vaporize, ablate, and coagulate oral soft tissue; and cut, shave, contour, and resect oral bone/teeth. Its high-water affinity and high-fluency pulses produce an exceptionally narrow zone of damage around the soft-tissue vaporization crater.
