Editing Laser lighting display (section)

==Safety==
Some lasers have the potential to cause [[Human eye|eye]] damage if aimed directly into the eye, or if someone were to stare directly into a stationary laser beam.  Some high-power lasers used in entertainment applications can also cause burns or skin damage if enough energy is directed onto the human body and at a close enough range. In the [[United States]], the use of lasers in entertainment, like other laser products, is regulated by the [[Food and Drug Administration (United States)|Food and Drug Administration]] (FDA) and additionally by some state regulatory agencies such as [[New York State]] which requires licensure of some laser operators.  Safety precautions used by laser lighting professionals include beamstops and procedures so that the beam is projected above the heads of the audience. It is possible, and in some countries commonplace, to do deliberate [[audience scanning]]. In such a case, the show is supposed to be designed and analyzed to keep the beam moving, so that no harmful amount of laser energy is ever received by any individual audience member.

Lasers used outdoors can pose a risk of "[[flash blindness]]" to [[aircraft pilot|pilots]] of [[aircraft]]<ref>{{Cite book|url=https://books.google.com/books?id=h99cSU9Du6AC&q=Lasers+used+outdoors+can+pose+a+risk+of+%22flash+blindness%22+to+pilots+of+aircraft|title=The Mobility forum: the journal of the Air Mobility Command|last1=Safety|first1=United States Air Mobility Command Chief of|last2=Safety|first2=United States Air Mobility Command Director of|date=1995|publisher=Chief of Safety, Air Mobility Command|language=en}}</ref> if too-bright light enters the cockpit. In the U.S., outdoor laser use is jointly regulated by the FDA and the [[Federal Aviation Administration]]. For details, see the article [[Lasers and aviation safety]].
In Europe the standard EN60825 is the reference concerning the conformity of the equipments of every laser-sources-production industries.

Maximum Permissible Exposure (MPE) is the maximum amount of visible laser radiation considered not to cause harm, for a given exposure time. In many European countries these exposure limits may also be a legal requirement. The MPE is 25.4W/m2 for a period of 250 milliseconds, which is equivalent to 1mW over 7mm circular aperture (the size of the human pupil).<ref>{{cite web |url=http://www.kvantlasers.sk/laser-safety-10-tips-for-safer-laser-show |title=Laser safety: 10 tips &#124; Kvant Laser Systems |access-date=2014-11-13 |url-status=dead |archive-url=https://web.archive.org/web/20150818024158/http://www.kvantlasers.sk/laser-safety-10-tips-for-safer-laser-show |archive-date=2015-08-18 }}</ref>
