Laser physics

Laser physics and laser-tissue interaction.

Within the last few years, lasers have gained increasing use in the management of cardiovascular disease, and laser angioplasty has become a widely performed procedure. For this reason, a basic knowledge of lasers and their applications is essential to vascular surgeons, cardiologists, and interventional radiologists. To elucidate some fundamental concepts regarding laser physics, we describe h...

Nonlinear physics of laser - irradiated micro - clusters

Abstract A nonlinear theory has been developed to describe electron response and ion acceleration in dense clusters that are smaller in size than the laser wavelength. This work is motivated by high-intensity laser-cluster interaction experiments. The theory reveals that the breakdown of quasi-neutrality affects the cluster dynamics in a dramatic way: the laser can create a positively charged i...
