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...
متن کاملChamber wall response to target implosion in inertial fusion reactors: new and critical assessments
The chamber walls in inertial fusion energy (IFE) reactors are exposed to harsh conditions following each target implosion. Key issues of the cyclic IFE operation include intense photon and ion deposition, wall thermal and hydrodynamic evolution, wall erosion and fatigue lifetime, and chamber clearing and evacuation to ensure desirable conditions prior to next target implosion. Several methods ...

متن کاملMODELING LASER–PLASMA INTERACTION PHYSICS UNDER DIRECT-DRIVE INERTIAL CONFINEMENT FUSION CONDITIONS Introduction
Introduction Laser–plasma interaction (LPI) processes taking place in indirectand direct-drive targets differ significantly in several ways. Plasma electron densities ne in hohlraum targets are typically a few percent of the critical density n m e c e = ω π 0 2 2 4 , so that the main instability mechanisms are stimulated Raman and stimulated Brillouin scattering (SRS and SBS, respectively), whi...
متن کاملProton radiography of a laser-driven implosion.
Protons accelerated by a picosecond laser pulse have been used to radiograph a 500 microm diameter capsule, imploded with 300 J of laser light in 6 symmetrically incident beams of wavelength 1.054 microm and pulse length 1 ns. Point projection proton backlighting was used to characterize the density gradients at discrete times through the implosion. Asymmetries were diagnosed both during the ea...
