Choice of lasers for laser angioplasty
Journal of Tongji Medical University, 1989Thrombi in test-tube, intraarterial thrombi and pig aorta wall were in vitro irradiated with continuous CO2 laser, short pulsal and ultrashort pulsal YAG laser (with pulse-width of 10 ns and 40 ps, respectively) and their double frequency laser and excimer laser with a wave-length of 308 nm and pulse-width of 20 ns.

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 ...

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.

Pulsed lasers and endocorporeal laser lithotripsy
Progrès en Urologie, 2021Endocorporeal laser lithotripsy (ELL) is currently the gold standard for the treatment of renal stones during retrograde intra-renal surgery (RIRS). The newly-authorised thulium fibre laser (Tm-Fibre) in now evaluated as a holmium:yttrium-aluminium-garnet (Ho:YAG) laser alternative, which is the most well-known laser source for ELL.

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

Clinical Techniques in Small Animal Practice, 2004
The laser is a tool that will augment the surgical techniques available to the veterinarian. When using the laser compared with traditional surgery there are multiple procedures that can be performed with much greater ease, and some procedures that previously could not be performed.

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,
