• Beam parameter product — In laser science, the beam parameter product (BPP) is the product of a laser beam s divergence angle (half angle) and the radius of the beam at its narrowest point (the beam waist).cite web|url=http://www.rp photonics.com/beam parameter… …   Wikipedia

• fluence — A measure of the quantity of x radiation in a beam in diagnostic radiology, either particle f., the number of photons passing an aperture of unit cross sectional area, or energy f., the sum of th …   Medical dictionary

• Convolution for optical broad-beam responses in scattering media — Photon transport theories, such as the Monte Carlo method, are commonly used to model light propagation in tissue. The responses to a pencil beam incident on a scattering medium are referred to as Green’s functions or impulse responses. Photon… …   Wikipedia

• Laser beam profiler — A laser beam profiler captures, displays, and records the spatial intensity profile of a laser beam at a particular plane transverse to the beam propagation path. Since there are many types of lasers ultraviolet, visible, infrared, continuous… …   Wikipedia

• Tophat beam — In optics, a tophat (or top hat) beam is a laser beam with a near uniform fluence (energy density) within a circular disk. It is typically formed by diffractive optical elements from a Gaussian beam. Tophat beams are often used in industry, for… …   Wikipedia

• Radiative transfer equation and diffusion theory for photon transport in biological tissue — Photon transport in biological tissue can be equivalently modeled numerically with Monte Carlo simulations or analytically by the radiative transfer equation (RTE). However, the RTE is difficult to solve without introducing approximations. A… …   Wikipedia

• Laser hair removal — Epilation by laser was performed experimentally for about 20 years before it became commercially available in the mid 1990s. Intense Pulsed Light (IPL) epilators, though technically not a laser, use xenon flash lamps that emit full spectrum light …   Wikipedia

• Spallation — In general, spallation is a process in which fragments of material (spall) are ejected from a body due to impact or stress. In nuclear physics, it is the process in which a heavy nucleus emits a large number of nucleons as a result of being hit… …   Wikipedia

• Fiber laser — A fiber laser or fibre laser is a laser in which the active gain medium is an optical fiber doped with rare earth elements such as erbium, ytterbium, neodymium, dysprosium, praseodymium, and thulium. They are related to doped fiber amplifiers,… …   Wikipedia

• Multileaf collimator — MLC shape of an X MLCs A multileaf collimator (MLC) is a device made up of individual leaves of a high atomic numbered material, usually tungsten, that can move independently in and out of the path of a particle beam in order to block it. MLCs… …   Wikipedia
