Umbau Zahnlabor DDT GmbH Georg DICKental research groups. Research in laser dentistry by relatively few investigators has included the laser spectroscopy, laser impacts of teeth and oral cavity of experimental animals, impacts of extracted teeth of man, and rarely, the actual impacts of teeth in patients.

Laser History and Theory,referred to as “optical masers.” The word “.” is an acronym for “Light Amplification by Stimulated Emission of Radiation,” and describes the emission process by which this intense beam of electromagnetic radiation is generated.

Basic Mechanisms of Laser Action on Living Tissue,erficial charring of a large wart on the knee of a patient. Even in the early days of laser research, a focussed beam of a low energy laser was able to make a hole in a razor blade and yet the same energy density had no effect on the normal Caucasian skin of the forearm.

Physiologic Pigments and Dyes for Increased Absorption of Laser Energy,diation of animals. Since laser is light, it was expected that dark masses would absorb more laser energy and, as a result, suffer greater degrees of damage. In our studies, colored tissues show more extensive necrosis with ruby, neodymium and CW argon lasers.

Laser History and Theory,’s involving microwave amplifiers. That the lasers derive their basis from maser theory is reflected by the fact that they were for sometime commonly referred to as “optical masers.” The word “.” is an acronym for “Light Amplification by Stimulated Emission of Radiation,” and describes the emission
