Anyone who has seen a professional laser show will remember it for a long time. Laser projectors that can project light shapes not only onto surfaces but also through the air are especially popular. To make the effects visible, a hazer is often used to fill the air with fine mist, allowing light beams and forms to extend visibly into the audience.
Lasers can be mounted on trusses like stage lights or placed on the floor. In some cases—especially when projecting effects above the audience—they are positioned outside the stage area. Each additional laser adds a new visual dimension to the event. However, high-power lasers must be handled carefully, as improper use may cause harm to eyes or skin. Therefore, safety guidelines must be followed. Laser output is classified between Class 1 and Class 4. For public use, a qualified Laser Safety Officer is required for Class 3a and 3b devices.
If a laser is used outdoors, it must be specifically designed for outdoor operation.
This abbreviation stands for the three basic colors red, green, and blue, which combine to create all other colors. Even white light effects are produced by blending these three. To achieve varied and impressive visual displays, RGB laser technology is highly recommended.
Laser technology has become affordable even for small productions. However, planning is essential to ensure the power rating, measured in milliwatts (mW), suits the environment. A 50 mW laser is ideal for a small club or party room. DJ lasers typically fall within Class 3b up to around 500 mW.
In addition to single-color lasers available at entry-level prices, the market also offers multicolor RGB lasers for smaller venues and high-power diode lasers for large events, classified as Class 4.
Since laser beams move dynamically, scan speed describes how fast the mirrors that deflect the beam operate. For precise laser graphics, a high scan speed—such as that of Galvo scanners—is recommended.
Nearly all professional lasers feature DMX connections to process control signals. They can be operated manually using a DMX controller or software or as part of a pre-programmed automated show. Many models also provide sound-activated and automatic modes. For users who prefer simple operation, some lasers include accessories such as remote controls or keypads for projecting custom text or effects.
This connection follows an international standard for transmitting control signals to laser devices. The data—typically sent from software—can be transmitted reliably over long distances via an ILDA cable. ILDA ports are usually found on professional laser units rather than entry-level models.
An interlock switch is essential for powerful lasers, serving as an emergency stop in case of malfunction. Many high-performance lasers also include a key-lock system to restrict use to authorized personnel.
Because laser beams concentrate light energy on a very small area, direct exposure can cause severe eye injuries. When deflected—as is typical in compact show laser systems with scanning units—the risk is greatly reduced.
Lasers and devices containing lasers are classified into safety categories according to international laser safety standards (IEC 60825). Most compact show lasers on the market, including those offered by us, belong to Class 3a or 3b. These devices must be used responsibly and in compliance with local safety requirements. For public events, a qualified Laser Safety Officer should supervise operation to ensure safe use.
For installations in public venues such as clubs, theatres, or event halls, systems may require inspection by local authorities or safety organizations. Always follow regional regulations and safety guidelines for the safe operation of show laser systems.
