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

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.

Accounts of Chemical Research, 2018
Research on graphene abounds, from fundamental science to device applications. In pursuit of complementary morphologies, formation of graphene foams is often preferred over the native two-dimensional (2D) forms due to the higher available area.

Lasers and laser–tissue interaction
Veterinary Clinics of North America: Small Animal Practice, 2002Light produced by a laser differs from incandescent light in that it is monochromatic, coherent, and intense; and it is these properties that allow lasers to be used as such unique tools in biomedical research and patient care. The effect of a laser beam on tissue is dependent on the optical and mechanical properties of the tissue, and the wavelength ...

Laser Physics and Laser Techniques.
1977Abstract : Substantial improvements have been made in the performance of the optically pumped 546.1 nm Hg laser. DC-pumped operation of sealed-off laser tubes has been demonstrated with no apparent lifetime limitations. Several new pump lamp designs have been developed and tested to overcome limitations set by emission line self-reversal, cataphoresis,

The first medical application of laser was reported by Dr Leon Goldman who, in 1962, reported the use of ruby and carbon dioxide (CO2) lasers in dermatology. In cardiovascular disease, early laser use was confined to cadaver vessels, animal models, and arteries located in freshly amputated limbs, until eventually work progressed to the use of laser ...

Urology, 1984
To date four laser wavelengths are commercially available which have urologic applications. The experience with all of these lasers is reviewed. The major urologic lesions treatable by the laser are: condylomata acuminata, superficial penile carcinoma, and bladder carcinoma. The carbon dioxide (CO2) laser is most applicable for external genital lesions
