Abstract
A dental laser system is disclosed having an erbium doped YAG laser which is excited so that the YAG laser produces a plurality of laser pulses. A novel delivery system for the YAG laser is disclosed which includes an elongated sapphire strand which consists of a single crystal. The sapphire strand has a diameter between 10 and 1000 microns so that it maintains its flexibility and the sapphire strand is encased within a flexible protective coating. The sapphire strand is also essentially devoid of water content.
