Depending on their hazardousness, laser systems are rated a certain laser class. Dangerous laser classes are 3B and 4: Additional safety measures are required, depending on the local laser safety regulations.
The manufacturer of a laser system is responsible for its correct classification - the classification only applies for the laser system and does not say anything about the actual hazardousness of potential audience scanning! In audience areas, the MPE must not be exceeded - this is also no problem with class 4 lasers in visible spectrum (all lasers offered by Laserworld emit in the visible spectrum and as cw-lasers only!), if appropriate measures are taken.
The laser class specification at the laser system is named AR = Accessible Radiation, whereas the power that's actually allowed to hit the audience is named MPE. The MPE is usually at the level of laser class 2. 

These laser classes are specified according to IEC 60825-1:07-2015 :

Laser Class 1

Class 1 lasers are, under normal circumstances, not hazardous, even when viewed with optical instruments. If the radiation is accessible, it is so weak, that no damage can occur to the human eye. If the radiation is hazardous, then it is encapsulated in a way, that it is inaccessible - even when the device is manipulated.
Note: Cutting lasers are usually encapsulated in such a way, so the device is rated class 1.

Laser Class 1M

Class 1M lasers emit a beam of 302.5 to 4000nm, which is either widened, or divergent.
For the whole beam the limit is 500mW (limit for class 3b). The pupil cuts only a portion of the beam, this portion does not exceed the limit of class 1.

When viewed with optical instruments class 1M lasers can be dangerous. Viewing with a loupe or a telescope/binocular can reverse the widening/divergence of the beam and thus exceed the limit for class 1.
Glasses are not considered optical instruments in this regard.
The manufacturer has to indicate which optical instruments can be dangerous

Laser Class 1C

Laser class 1C has been newly established in IEC 60825 version 07-2015 and covers laser systems that are designed for direct contact with the "objective", like e.g. the skin.
This can be laser systems for hair removal, reduction of wrinkles, tattoo removal and treatment of akne. Included are laser systems for home use as well.
Protection measures for these laser systems must ensure to not allow any emission of radiation that exceeds the level of laser class 1. Usually the laser class 1C units have special contcat sensors that prevent laser emission if the laser is not used in a safe way. The electrical conductivity of human skin is often used for these kind of safety measures.

Laser Class 2

Class 2 lasers emit only visible radiation not exceeding 1mW power. Accidentally looking into the beam does not create damage to the eye, even when using optical instruments.
Warning: Looking into the beam intentionally may be dangerous (as the reflex of closing the eye or turning away is not working)!

Laser Class 2M

Class 2M lasers emit a visible beam (400-700nm), which is either widened or divergent.
The limit for the whole beam is 500mW (limit for class 3b). The pupil cuts only a portion of the beam. This portion must not exceed the limit of class 2.

When viewed with optical instruments class 2M lasers can be dangerous. Viewing with a loupe or a telescope/binocular can reverse the widening/divergence of the beam and thus exceed the limit for class 2.
Glasses are not considered optical instruments in this regard.
The manufacturer has to indicate which optical instruments can be dangerous.

Laser Class 3R

Class 3R emit a visible beam (400-700nm) that does not exceed 5 times the limit of class 1 for invisible, or 5 times the limit of class 2 for visible radiation (=5mW).
R stands for relaxed, lasers of class 3R do not require the same safety measures as lasers of class 3b and 4 do.
Warning: Class 3R lasers can damage the eye, even when only looking into the beam for a short time. Do not look into the beam!

Laser Class 3B

Lasers of class 3B emit in continuous wave mode a power of maximum 500mW. Direct viewing of the beam will cause damage to the eye!
When viewing the image of the beam/spot on a diffuse reflecting wall, the eye will not be damaged. (Distance to the spot 13cm, viewing time less than 10sec.)
Warning: Class 3B lasers can damage the eye, even when only looking into the beam or into specular reflections for a short time. Do not look into the beam!

Laser Class 4

All other lasers are class 4. There is no limit for class 4 lasers. Beam, specular reflections and diffuse reflections can very dangerous for both eyes and skin!
When viewing diffuse reflections, the MPE level of the reflection has to be assessed. 
Class 4 lasers can damage eye and skin by direct or indirect radiation!
The radiation of class 4 lasers can release toxic fumes from certain materials and ignite inflammable or explosive materials.

Buy Show Laser Light Systems

Laserworld is a world leader in the field of manufacturing and distribution of show laser light systems. The product portfolio ranges from small, entry level laser light systems (effect lasers, club lasers, party lasers) up to high end professional lasers. Every product and product series targets a certain customer group, so the laser systems in the Laserworld product portfolio complement each other, which results in heterogeneous customer groups: musical equipment retail stores, music stores as well as nightclubs, amusement parks, rental and production companies are just a small extract of them.
Laserworld runs an online store for show laser light systems on sale. It is possible to buy laser light systems directly there or purchase them at one of our countless distribution partners. Commercial customers are encouraged to register as dealer.

Rent Laser Systems

It does not always make sense to buy, but to rent laser show systems. Laserworld holds a large stock of laser systems for rent.. The rental laser systems are available for worldwide shipping and can also be rented together with professional laser operators. We only rent out high professional laser show equipment, mainly built by RTI. So products of the PIKO, NANO and NEO Series are available. And of course we offer Showcontroller, Pangolin and Lasergraph DSP laser show control systems for rent as well.
Laserworld holds larger stock of RGB white light laser systems with 10W and more. The online rental price list helps in selecting the right laser for rental and helps to calculate the rental price. It is also possible to select laser accessories for rent, such as haze machines, smoke machines or MIDI controllers.

Laser Show Production

Long year experience of show partners and many references from past laser show and multimedia show projects where lasers manufactured by the Laserworld Group came into action, make us the right partner for any type of laser show production or laser show project. No matter if it’s a fixed installation of laser systems or multi-media projections, or if it’s a temporary show: Our experts help in laser show planning, design, on-site implementation and laser show production. We offer turn-key multimedia show solutions as well as Laser Show productions in part or embedded to other show productions, like it happens at big stage shows, festivals or concerts. Time-coded, pre-synchronized shows can be done as well as live laser shows: We have experts for both types, they can handle even extremely complex synchronization scenarios.
It is also possible to do small-scale laser shows for little money: Just tell us about your plans for your laser show and we help you in specifying a show that meets the show budget.

Laser Show References

Many references of laser shows and multi-media shows where laser systems manufactured by the Laserworld group came into action accumulated over the past years, so we documented them in pictures and videos in our portfolio section. Of course, these references only show a small part of the laser shows and multi-media shows our partners have done throughout the years, as many of our customers did not want us to show their project in our references – mainly as these were commercial laser applications or corporate laser shows, which were not meant to be publicly shown. Nevertheless we prepared a good number of references, and we keep on adding more.
The partners of the Laserworld Group did laser shows and multi-media projects at many different occasions and for many different applications. Most common places laser shows are displayed at nightclubs, festivals, amusement parks and at corporate shows. Also many famous artists and musicians rely on laser show and multimedia support for their stage shows. Besides that, lasers were used at weddings, for product presentations or for architecture and mapping.
