Chemische Laser (chemical lasers)
1989Bei einem chemischen Laser wird die Besetzungsinversion und die Laserstrahlung direkt durch eine chemische Reaktion erzeugt [vgl. Kompa 1973, Chester 1976, Gross & Bott 1976, Ultee 1979]. In diesem Sinne gelten die gasdynamischen CO2 Laser (vgl. Kap. 12.6.2) nicht als chemische Laser.

After a general discussion of the merits of glass vs. crystals as host materials for laser ions, a summary is given of the various glass lasers. Because of its importance as an efficient, room temperature laser the properties of neodymium are considered in greater detail.

Lasers have been proposed as an adjunctive method of conventional root canal therapy in order to enhance the effect of irrigation solution and, thus, to improve the smear layer removal from root canal system. The aim of the present thesis was to evaluate the efficacy of hard tissue lasers (Er: YAG laser, Er, Cr: YSGG laser) for smear layer removal from

A review is given of the present status of gas discharge lasers, with particular attention to developments reported in 1965 and early 1966. Following a brief history, gas lasers are classified by types-neutral atom, ion, and molecular-and a comparison is given of the properties of the various types.

Concepts and methods of laser labyrinthectomy have been proposed based on experimental studies in which the macula utriculi was irradiated with an argon laser beam through the oval window. In our previous reports, a single application of the beam (1.5 W, 0.5 s) eradicated the guinea pig macula within 5 weeks. The contour of the membranous labyrinth was
