7. Low Power Laser in Medicine and Surgery — State of the Art

Author

Subjects
medicine.medical_specialty, business.industry, Short pulse laser, Thermal effect, Pain relief, Laser Acupuncture, Laser, Power (physics), Surgery, law.invention, Laser application, law, medicine, business
Abstract

Laser applications in medicine and surgery have been started by using high power to coagulate, to vaporarize the biological tissues — it means by use of thermal effect. Next application of laser is considered to be using pressure effect to destruct biological stone by application of short pulse laser. Recently, the use of low power is becoming one of the topics of laser applications in medicine.

Abstract

With tunable short pulse laser sources it has now become possible to examine the kinetics of excitons in semiconductors with detail not possible previously. Here we illustrate the point in the case of excitonic phenomena at low densities for three compound semiconductors, Cu2O, GaSe, and Cd1−xMnxTe, the range of phenomena varying from energy-dependent free exciton collisions to thermalization processes characteristic of localized excitons.

9. Photoablation Threshold of Human Aorta as a Function of Wavelength

Author

B. Biamino, G. Müller, K. Dörschel, H.-P. Berlien, and H. Kar

Subjects
Human aorta, Materials science, business.industry, Laser Angioplasty, Short pulse laser, Photoablation, Laser, Peripheral, law.invention, Wavelength, Catheter, Optics, law, business, Biomedical engineering
Abstract

In Fig. 1 an artist’s view of laser angioplasty is shown. The goal is to transport energy from short pulsed lasers through fibers via a catheter system, probably a balloon-dilatation catheter, to photoablate plaques in coronary and peripheral arteries.
