267:. The basic idea is that on every wavefront exists a forward propagating spherical wavelet of light. The initial wavefront manifests itself in the form of a straight line, as if the subject was seeing a wave coming in towards themselves in the water. Aspects of the spherical waves that divert sideways are cancelled with the sideways components of the wave points on each respect point on either side. Diffraction is the primary method that many simple laser projectors work. Light is projected out towards multiple points.

236:); other methods of creating images through the use of galvanometer scanners and X-Y control voltages can generate letters, shapes, and even complicated and intricate images. A planar or conical moving beam aimed through atmospheric smoke or fog can display a plane or cone of light known as a "laser tunnel" effect.

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

Uninterrupted stationary beams from one or more laser emitters are used to create aerial beam effects, which are turned on and off at varying intervals to create a sense of excitement. As the laser beam is not manipulated in any way, this could be considered the simplest form of a laser light show

to which a control voltage is applied. The beam is deflected a certain amount which correlates to the amount of voltage applied to the galvanometer scanner. Two galvanometer scanners can enable X-Y control voltages to aim the beam to any point on a square. This is called vector scanning. This

without refocusing for the differences in distance, as is common with video projection. This inherently more focused beam is also extremely visible, and is often used as an effect. Sometimes the beams are "bounced" to different positions with mirrors to create laser sculptures.

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

Laser light is useful in entertainment because the coherent nature of laser light allows a narrow beam to be produced, which allows the use of optical scanning to draw patterns or images on walls, ceilings or other surfaces including

Tour which also featured the famous "Flying Saucer". This is now highly regulated in the U.S., to the point where almost no U.S. shows have laser beams that go into or close to the audience.
306:. 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.

Laser light shows fully emerged in the early 1970s and became a form of psychedelic entertainment, usually accompanied with a live musical performance on stage or pre-recorded music.
