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
dierence between no show and a great show.
When outdoors, lasers mainly reflect o dust and mist in the air but due to unpredictable wind conditions we can never
make sure the hazers or smoke machines will be eective 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?

Standard full colour analogue lasers use three primary colours: Red, Green and Blue. By mixing those together you can
pretty much get any secondary colour:
RGBY laser projectors use three primary colours (Red, Green, Blue) and additional yellow colour.
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 dierent 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.
Red + Blue = Magenta
Red + Green = YellowYellow
Green + Blue = Cyan
Red + Green + Blue = White
Red + Blue = Magenta
Yellow Laser moduleYellow Laser module = YellowYellow
Green + Blue = Cyan
Red + Green + Blue + YellowYellow = White
Colours
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 actually produced by one single laser beam being moved by these mirrors very quickly.
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 second and that is usually represented in Points Per Second at a certain scanning angle, i.e. 8 degrees.

Laser Safety First!
2.2
Before proceeding any further, please read the following safety page very carefully. It could help you
avoid dangerous and hazardous situations which could lead to serious injury or property damage.
!
Before proceeding any further, please read the following safety page very carefully. It could help you
avoid dangerous and hazardous situations which could lead to serious injury or property damage.
!
Unless you are very competent with the use of lasers and about the laser safety, make sure you at least follow these basic
laser safety rules:
1. Never look directly into a laser beam.
2. Never look directly into laser aperture if the laser system is switched on.
3. Be aware that lasers can burn the eye retina, skin or cause fires if not used correctly.
4. Never perform Audience Scanning – that’s when laser beams and eects hit an audience directly. Always
project with the laser above audience head level – at least 3m above floor level.
5. When performing outdoors, avoid pointing the laser at aircrafts, buses, trains, etc.
6. Never leave the laser system unattended when it’s switched on.
7. Always check for reflective surfaces within the laser range – these can be very dangerous (i.e. mirror
behind the bar in a club could bounce the beam into bar attendant’s eye).
8. Never hesitate to use the Emergency STOP if you think there’s a fault within the laser system or a
potential danger to a person/object caused by the laser performance.

Control System
2.4
The overall performance of any KVANT laser system is also dependent on the control system that you use for operating
the laser as well as the correct device configuration in the laser control software.
Please make sure all the laser settings in your control system are set correctly before you start using your Kvant laser
display system.

Scanning System
2.5
The product warranty does not cover the damages to the scanning system caused by improper use of the scanning
system or by incorrect programming. Therefore it is essential to understand how the scanning works and where are the
limits of it. In this manual we will explain only the basics of it but it is the responsibility of every user to educate themselves
so they can avoid damage being caused to the scanning system and costly repairs.
A laser beam comes from a laser module and hits the two moving mirrors of the scanning system. These mirrors are
mounted on the scanner shafts and are moved by the scanner rotors, one on X and one on Y axis.
An eect such as tunnel (circle) is displayed by a repetitive mechanical movement of the scanners. For each scanning
system and eect, there’s a maximal scan rate that is defined by mechanical load, scanner mirror size and weight,
complexity of displayed picture and size of the projection (an angle under the laser beam is being projected). A dierent
scanning systems have dierent scan- rate limits. It is essential to operate the scanning system at scan-rates within its
maximal limit at all times to prevent it from overload damage.

10 |41 RGBY Laser Projectors - v170120 Kvant Lasers s.r.o.
EN
Each eect (picture) contains a dierent number of graphical points which defines the actual shape of the eect. The more
points an eect contains, the lower the maximum scan rate will be in relation to the scanning angle.
As an example we’ll work with the star eect shown below and with the parameters of quality scanning system:
Let’s say the star eect is made of 300 graphical points (including non-visible blanking points) and we know that the
maximal scan-rate of our scanning system is 35kpps @ 8 degrees (= 35.000 points per second at 8 degrees projection
angle). We also know that we display the star 35 times per second which is a default frame rate of the control software
we are using.
So we need to display 300 points 35 times per second = 10.500 pps. This means that we could display 3 of these
stars beside each other within one single laser eect and that it would be quite close to the scanner limit (3 × 10.500
= 31.500pps). This however applies ONLY if the scanning angle is not more than 8 degrees on both axes! If we start to
increase the size of the projection (scanning angle) it is necessary to either lower the number of points within the eect
or drop down the scan-rate in the control software (FPS) to a safe level – which may result in flicker.
From the example above we can also determine how many points this scanning system is able to project if the scanning
angle is not more than 8 degrees:
35.000 points / 35 Frames Per Second = 1.000 pps. This is the absolute maximum of how many points we should be using
when programming an eect if the scanning angle is not more than 8 degrees.
In the following pictures you see the same star eect scanned at dierent scan rates at full scanning angle (60 degrees).
Picture 1: the scan rate and/or number of points is too low. The corner points are more visible than the lines between them
and the whole eect flickers. The scan-rate and/or number of points needs to be increased.
Picture 2: the scan-rate and/or number of points is about right. The whole eect has more or less the same intensity and
does not flicker.
Picture 3: further increasing of the scan-rate and/or number of points results in the eect starting to distort, firstly around
corners only. This indicates that you are exceeding the maximal scan rate of the scanning system! If you operate the
scanning system at scan-rates higher than the maximum scan-rate of the scanning system the scanners will get damaged
irreversibly due to overheated coils damaging rotor magnets.

Maintenance
To clean the aperture output window use a soft cloth and medical grade isopropyl alcohol. If necessary, you can remove
the aperture output window by loosing the 4 socket bolts and clean the inside of the window as well.
Aperture Window
Use compressed air for cleaning the bottom part of the laser system. There are cooling fans located at the bottom of the
heat sink and they are vital for correct operation of the laser system. Please always ensure that they are spinning freely.
You should perform this service every 2 months if the laser is used regularly or even more often if it is used in dusty
conditions.
Cooling Fans
The cleaning of the internal optical components should be performed by an authorised technician only. Incorrect
techniques or wrong choice of chemicals used for cleaning could cause serious damage to the laser system. Due to the
fact that the optical compartment is split and sealed from the rest of the laser system it shouldn’t be necessary to perform
this procedure more often than once a year.
Drying agent cartridge (silica gel desiccant) helps to prevent water condensation inside the optical compartment of the
laser system, which is much needed in high temperatures and high humidity environments. The desiccant cartridge is
installed on the inside of the optical compartment cover.

It is essential to regularly inspect the condition of the silica gel granules inside the cartridges. That can be
done through the opening in the middle of the cartridge. If the colour of the granules inside the cartridge
is green, instead of brown (brown is when they are dry), it means they are soaked, and they must be dried
out. Inspect the cartridge every time you open the optical compartment, or at least once a month.

1. Detach the cartridge from the cover and place it into the conventional oven - do not use microwave!!!
2. Heat the oven to 120ºC (250ºF) and leave the cartridge inside for about 2-3 hours, until all the moisture is released.
3. Insert the cartridge back into its place and close the optical compartment cover as soon as the cartridge cools down.
That way, it will absorb the maximum amount of moisture from the inside of the optical section.
The drying out process is pretty simple:
If the granules don’t turn brown during this process, they must be replaced with new ones.
