Abstract
An improved dental laser system includes a DC power section that rectifies its AC electrical input energy in a format suitable for both CW and pulsed operation, an RF power supply operating in a range of about 40 to 125 MHz and configured for both CW and high peak power pulsing operation, a sealed-off, RF excited CO2 waveguide or slab resonator laser filled to a gas at a pressure between about 260 to 600 Torr (or about 34,700-80,000 Pa), and a beam delivery system to steer the beam from the output of the laser to the mouth, such as the patient's mouth.
