9. 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 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 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 How far does it go 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 Colours 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 Red Blue Magenta Red Green Yellow Green Blue Cyan Red Green Blue White Of course the
10. n rate and maximal number of points in an effect Each effect picture contains a different number of graphical points which defines the actual shape of the effect The more points an effect contains the lower the maximum scan rate will be in relation to the scanning angle As an example we ll work with the star effect shown below and with the parameters of the scannerMAX 506 Compact Let s say the star effect is made of 300 graphical points including non visible blanking points and we know that the maximal scan rate of this 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 within one single laser effect and that it would be quite close to the scanner limit 3 x 10 500 31 500pps This however applies ONLY if the scanning angle is not more than 8 degrees on both axis If we start to increase the size of the projection scanning angle it is necessary to either lower the number of points within the effect or drop down the scan rate in the control software FPS to a safe level which may result in flicker Page 5 KVANT From the example on the previous page we can also determine how many points this scanning system is able to project if the scanning an

12. 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 that use cheap DPSS technology 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 actually produced 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 second and that is usually represented in Points Per Second at a certain scanning angle i e 8 degrees Page 2 KVANT Laser Safety First Before proceeding any further please read the following safety page very carefully and It could help you avoid dangerous and hazardous situations which could lead to serious injury or property damage Any laser system classified as a Class 4 laser must be used with caution If you are not an experienced laser operator we would strongly recommend that you attend a laser display safety course as soon as possible and ideally before this laser system is used in
