What you should know about a laser system

So let’s say you are after a professional laser display system, either for your home, a small club, or a large venue. Or maybe you would like to do some outdoor advertising with lasers.

In any case, you should know some basics about lasers so when you choose one and pay for it, it will fit desired application and you won’t regret your choice.

There are far too many laser display systems available on the market so making the right choice can be tough. But there are some basic rules here which one should follow.

How much power is needed for an indoor and outdoor laser show?

The suitable laser display system for an indoor show should output anywhere between

1 to 12 Watts of the white light laser. In certain situations, more power may be needed, but that would be mostly for shows in large arenas. For clubs and spaces that would take between 100 to a few thousand people the laser display system such as KVANT Club max is a great choice.

Any outdoor laser display will require a lot more power as it is impossible to make sure the artificial haze or smoke will stay where we need it – mainly due to the unpredictable direction of the wind. For outdoor shows, we recommend lasers from 20 Watts upwards such as the Spectrum range of KVANT systems.

What about scanning speeds?

The scanners are two relatively small but fast-moving mirrors that steer the laser beam into the desired position. If the beam is moved around the same shape (like circle, square, etc.) fast enough, it appears static to us humans. And that’s how all the laser effects are created – by a single laser beam.

It is pretty easy for any modern scanners to do a static circle, but you want a lot more. For a good show, you will need a system that can handle several shapes at the same time. So in terms of scanner speeds, you should aim for a laser display system that offers at least 30Kpps (or 30.000 points per second) scanning, such as KVANT Club max, Atom, or Spectrum lasers.

More is better when it comes to scanning speeds and these days KVANT offers scanners with speeds up to 90Kpps at 8 degrees scanning angle.

What laser source? Diode laser, OPSL or DPSS laser?

These are the names of different types of laser sources used in the laser display business and although they are some similarities amongst them the laser light and its color is generated in each of them differently.

Diode lasers are now probably the most common and that’s mainly because of their price to performance ratio. This technology is used by virtually all laser display system manufacturers and it can give some amazing results.

But you should research well before purchase – it takes a lot of expertise to produce a pure and fine beam using this technology. And not many manufacturers are up to the task.

Using OPSL technology is a great choice if you are after a system with superb beams and colors. With OPSL it’s all down to how much money you are willing to pay. OPSL modules are very expensive when compared to Diode lasers and although the results are better, for most it will be hard to justify such a huge difference in price.

DPSS lasers are not used that often in this industry anymore. Although there are some absolutely superb DPSS lasers that can’t be matched with anything else, their price also can’t be matched and as such, they are used for high-end scientific research and similar applications.

Not long after the green laser diode was released to the market, all the usual and cheaper DPSS laser heads used by virtually every manufacturer were replaced with much more efficient Diode lasers.

Laser safety! What is needed?

Your laser display system needs to be fitted with absolutely every single laser safety feature required by the law of the country it will be used in. The European and US law is pretty strict and failing the safety legislation could result in pretty big problems.

Most professional manufacturers such as Kvant Lasers have all the safety features 100% covered, but there are many others who don’t, so be cautious!

Control system

These days most of the hi-end lasers would be fitted with a laser control interface and come with appropriate software so you can get it up and running straight from the box.
