light is very powerful and although it doesn't sound
like much it can burn eye retinas,skinandclothes or
even start a fire.
What makes the laser visible?
Mainly it is the particles of dust in the air that the
laser beam hits on its path. That's why we "laser-
ists" 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 substitutefor the lack
of dust, haze and smoke.
How far does it go?
Depending on the power output of the system and
weather conditions, the laser can be visible formiles
–that is why we need to be cautious about air crafts
when performing outdoor shows. And if you get a
system that is powerful enough then yes, it can-
reach the Moon.
COLOURS
Standard full colour analogue lasers use three pri-
mary colours: Red, Green and Blue. By mixing those
together you can pretty much get any secondary

colour:
• Red + Blue: Magenta
• Red + Green: Yellow
• Green + Blue: Cyan
• Red + Green + Blue: White
Of course the number and precision of the colours
is determined by the modulation, stability and
linearity of the system. If the system is not stable
enough, it will produce different colours every
time it is used, making it virtually impossible to
match the colours of two systems at any one time.
This is very often the case with systems from far
east manufacturers and with re-branded lasers
that are being presented as European makes.
SCANNING SYSTEM
A scanning system is essentially two tiny mirrors,
each moving on X or Y axis. By working together
they can "scan" the laser beam in all directions.
Once a shape is scanned more than 20 times per
second, it appears static to the human eye. So any
shape drawn by a laser is actuallyproduced by
one single laser beam running around like crazy.
Every scanning system has a mechanical limit of
how fast it can move its mirrors and therefore
how many points it can display at any one sec-
ondand that is usually represented in Points Per
Second at a certain scanning angle, i.e.8 degrees.
