Light Amplification by the Stimulated Emission of Radiation.

Why use lasers?

There's no other light like it. The most vivid, saturated color palette available. A contrast ratio unsurpassed by the best film and video technologies. The ability to reach out in three dimensions and shower an audience with cascades of beams or embrace them in waves of moving light.

  • It's about enchanting an audience with dreamlike visions.
  • It's about exciting crowds with visual effects that move faster than any other light-form.
  • It's about engaging clients and customers with captivating images that move with a liquid-smooth animation style.
Today's laser displays are creating visions that others only dream of.

The advantage of laser light

The primary advantage of laser light is that it truly is a unique high-tech lighting source, not normally seen by the average person. This makes lasers perfect for special applications and events.

There are two main types of laser displays: beams and graphics.

For aerial beam shows, the laser light is seen in mid-air, either as glowing beams or scanned to create shapes such as cones and planes of light.

What makes aerial laser beam shows especially effective is the tight beam. When used with theatrical fog, a plane of laser light literally cuts through a 1 cm cross-section of the fog, creating a sharp, eerie pattern of light and dark swirls. From just one laser projector, you can produce an amazing “Star Wars” effect of laser beams shooting throughout a room in many different directions.

In contrast, laser graphics are projected onto a screen, wall or other surface. The tiny dot made by the laser beam is moved quickly by computer-controlled mirrors, to draw out images, text and logos.

Of course, both beams and graphics are preferred to be used simultaneously. A popular configuration for shows is to have a central screen where graphics are front- or rear-projected. Flanking the screen on either side are aerial beam projectors, used to send beam patterns out, over – and even into – the audience.

This unique effect, which can’t be duplicated by conventional lighting, is probably the most popular use of lasers worldwide. Unlike most other media, which occur far from the audience and are passively enjoyed, laser beams actually reach out and touch the audience. This provides a much stronger emotional link between artist and audience
