Een laser is een lichtbron die in staat is een smalle coherente bundel licht voort te brengen. Het licht van een laser is daardoor monochromatisch en directioneel, in tegenstelling tot de meeste andere lichtbronnen, die in allerlei richtingen licht uitzenden in een breed spectrum van golflengtes en fasen. Ook zorgt laserlicht altijd voor een lichtbundel die niet of nauwelijks convergeert of divergeert. Het woord laser is oorspronkelijk een acroniem van L ight A mplification by S timulated E mission of R radiation, in het Nederlands: Het woord is echter inmiddels zo ingeburgerd dat het niet meer gezien wordt als een afkorting. Laser safety is the safe design, use and implementation of lasers to minimize the risk of laser accidents, especially those involving eye injuries. Since even relatively small amounts of laser light can lead to permanent eye injuries, the sale and usage of lasers is typically subject to government regulations. The first document is an illustrated booklet giving an introduction to lasers and laser safety. It includes information on laser beam interactions with the eye and skin, legislation governing. 1. Lasers. Lasers are now widely used during the course of our daily lives. They can be found at home, in the workplace and they are used for many different applications. urtekram shampoo review The National Institute for Laser, Plasma & Radiation Physics (INFLPR) is an independent, national importance research institution established by the Government of Romania. 12/11/ · RADIATION & LASER SAFETY. The ultimate aim when working with any source of radiation is to minimise the doses that staff and students receive. This is what is known as the ALARA principle - keeping doses "As Low As Reasonably Achievable". This information is designed for Heads of Schools, Disciplines, Units, Chief Investigators and all research staff where ionising radiation is used. The safety limits that exist for human exposure of laser radiation are radiation to reduce the risk of injuries. These values, however, give very little information on what tissue damages that may be expected at various elevated exposure levels. Similarly, the Swedish Radiation Protection Authority SSM has very little information on how such tissue damage is related to the impairment of the vision. The purpose of this study was to investigate what dose of laser radiation, in terms of laser and exposure time, may be associated with eye damages.

This document interprets FDA regulatory lasers as they apply to laser pointers, explains the power limits for these products, and the applicable requirements for information for safe use and for promotional materials. The document also discusses inappropriate use of high-powered, battery-operated, portable lasers. Lasers are generally classified according to the radiation posed by the amount and type of light they emit. Laser pointers are hand-held lasers that are promoted for pointing out objects or locations. Such laser products can meet one of two definitions for laser products.

A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic duwed.aniagranb.se term "laser" originated as an acronym for "Light Amplification by Stimulated Emission of Radiation". The first laser was built in by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur.
