Have you ever wondered how a laser shows work? How about what causes a laser to be so much brighter and vibrant than regular lighting? These concepts can be difficult to fully grasp as they involve both mathematics and physics in their explanations. Here I will attempt to simplify the mechanics of the laser into layman's terms so that you may have a better understanding of just what's going on inside a laser device. If you'd like a more complete explanation or have any other inquiries about laser lighting be sure to contact the professionals at London Lighting Hire.


The first thing you need is a light source. The type of light you use will depend on the desired colour and brightness of the light. The type of colour produced is dependent on the wavelength of light. Each colour of the rainbow coincides with a certain wavelength and all the wavelengths as a whole form what we know as the visible light spectrum. Longer wavelengths coincide with the red and orange side of the spectrum, while shorter wavelengths coincide with the blue and violet portion. Brightness, as you may know from conventional light bulbs ...
... is measured in watts. A watt is actually a measure of the rate of energy conversion, so the more watts you have the brighter the light will be. It's important to note that lasers actually produce the most watts out of any other device known to man, with a few of them able to produce a petawatt which is equal to a quadrillion watts, but only for a fraction of a second. Of course this is just a simple explanation of the light source used in lasers; London Lighting Hire would be happy to elaborate if need be.


The next aspect of a laser is the projector. This component is made up of tiny moving mirrors that can direct the light into a single concentrated beam or split it into numerous beams to produce cones, fans, and tunnels. The mirrors can also be used to produce outlines of images that can depict a story or often a company logo or trademark. If you're looking to have a custom show made using any of the above effects, than London Lighting Hirewill work alongside you to make whatever it is that you envision, a reality.


The final but possibly most important part of a laser show is how the laser is used. There are endless possibilities in this department, from just a single coloured laser all the way up to hundreds of lasers and graphics set to music.
