What is a laser and
how does it work?
The laser is a bunch of energy waves (streams of photons called radiation) with the same amplitude and faze that are
flowing in the same direction; meaning they are coherent – they stick together and form a laser beam.
The width of a single wave is measured in nano-meters and defines the colour and visibility of the laser beam. The visible
spectrum of the human eye is roughly between 400nm and 700nm, going from violet to a dark red colour. A human eye
is most sensitive to a green light of around 555nm, meaning that a 1W of green laser will always appear more visible than
1W of any other colour laser. 1W of quality laser light is very powerful and although it doesn’t sound like much it can burn
eye retinas, skin and clothes or even start a fire!
What is a LASER?
Mainly it is the particles of dust in the air that the laser beam hits on its path. That’s why we “laserists” use haze or smoke
machines to make lasers more visible. Too much of the haze or smoke will kill it, but the right amount will make all the
difference between no show and a great show.
When outdoors, lasers mainly reflect off dust and mist in the air but due to unpredictable wind conditions we can never
make sure the hazers or smoke machines will be effective enough. And that’s why we use high power lasers for outdoor
shows – to substitute for the lack of dust, haze and smoke.
What makes the laser visible?
Depending on the power output of the system and weather conditions, the laser can be visible for miles – that is why we
need to be cautious about aircrafts when performing outdoor shows. And if you get a system that is powerful enough then
yes, it can reach the Moon.
How far does it go?
