Most people know what is a laser show. OK, let’s call it properly – a laser display.
You’ve probably seen a laser display at some point in your life during a concert, festival or a smashing party.We all know the colourful beams, tunnels, waves, sheets of light and other amazing space-like laser effects that blow our mind. Sometimes we can also see laser graphics and animations being projected with lasers into haze, water or onto a wall. And sometimes the laser displays can be done in an artistic or abstract way.
But have you ever thought how does it actually work? Let us explain.
The core of any proper laser display is quality kit such as one of the Clubmax series lasers made by Kvant. In this article we consider the use of pro-level equipment made from quality components only and with high performance scanning system installed (able to run at least at 30,000 points per second or more).
No cheap and cheerful Chinese flashing toys will allow you to do any of this properly.
Any laser show effect is created essentially by just one single laser beam that is being generated inside the laser display system – how this works is beyond the scope of this article and here we’ll focus on the outcome of what happens inside of the system.
This laser beam is then pointed to something we call “scanning system”. The scanning system can be thought of as a couple of fast moving mirrors, where one moves the beam on X axis and the other one on Y axis. The laser beam hits first mirror, then the second mirror and exits the aperture. This is how we steer the beam into desired positions and basically how we draw with it. And if we draw the same shape 20 or more times per second, it will appear static to us, humans.
That so well known tunnel effect is basically a single laser beam that runs around the circle like crazy (it draws the circle). If you look towards it, you see the tunnel (a cone of light).
When a laser show is put together, the quality of final result depends not only on the quality of laser display equipment used for the show, but also on how skilled is the laser programmer.
The laser display can be programmed to a piece of music or performed life, it can be time-coded to any compatible device or other effects.
These days the best laser displays are those that are combined with other types of entertainment media such as SFXs, laser mapping, video mapping, 3D holographic projections and live performance. KvantLasers company doesn’t only manufacture professional laser systems such usClubmax, Atom and Spectrum, but also provides the multimedia show production using all the media mentioned above.
