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.

Survey Review, 1974
Abstract Because lasers are being used increasingly in surveying, knowledge of the way in which a laser beam can damage the human eye is essential. This article describes the process by which damage to the retina may occur, and examines some methods by which this hazard can be reduced, if not eliminated.

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.
