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.

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 ...

2010
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 ...

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,

Multidimensional quantum well laser and temperature dependence of its threshold current
, 1982A new type of semiconductor laser is studied, in which injected carriers in the active region are quantum mechanically confined in two or three dimensions (2D or 3D). Effects of such confinements on the lasing characteristics are analyzed. Most important,

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
