Essential Information About Lasers

Anyone who has ever seen a professionally designed laser show will never forget the experience. Laser projectors that not only project light shapes onto surfaces but also beam them through the air are especially popular. To make the light effects stand out, a hazer is used to fill the room with artificial mist, creating visible beams and 3D shapes that extend into the audience.

Setup

Lasers can be mounted on trusses like stage spotlights or placed directly on the floor. In some cases—such as when projecting beams above the audience—lasers are positioned outside the stage area. Each additional laser enhances a show by adding new visual dynamics. However, high-power lasers must be used carefully, as improper handling can lead to eye or skin injuries. Therefore, certain safety standards must be followed. Laser output is divided into Classes 1 through 4, and for public events, a certified Laser Safety Officer is required for Class 3a and 3b systems.

If a laser is used outdoors, it must be explicitly rated for outdoor operation.

With 400 mW of output power, this laser is a great choice for entry-level users and mobile DJs.

RGB Show Lasers

This abbreviation refers to the three primary colors: red, green, and blue, which serve as the foundation for creating all other colors. Even white light effects are produced by combining these three. To create visually impressive and dynamic displays, RGB laser technology is highly recommended.

Power and Scan Speed

Laser technology has become affordable for smaller setups, too. However, it’s essential to plan carefully to ensure the power output, measured in milliwatts (mW), fits the intended space. For example, a 50 mW laser is perfect for a small party room. DJ lasers typically fall within Class 3b, up to around 500 mW.

Besides single-color lasers available at budget prices, the market also offers multi-color RGB lasers for small venues and powerful diode lasers for large-scale productions, typically classified as Class 4.

Because laser beams move dynamically through space, scanning speed indicates how quickly the mirrors redirect the beam. For clear and smooth laser graphics, a high scan speed—such as that offered by Galvo scanners—is ideal.

Control

Almost all stage lasers feature DMX connections for control signal processing. These can be operated manually via a DMX controller or DMX software or integrated into a pre-programmed automated show. Many models also offer sound-activated and auto modes. For users who prefer simpler setups, some lasers include accessories like remote controls or small keypads for typing custom text to be projected by the laser.

This laser can project graphics, logos, and text and features a professional ILDA interface.

The ILDA Connection

This connection follows a standard protocol for transmitting control data to laser devices. The control signals—usually sent by software—can be transmitted reliably over long distances using an ILDA cable. ILDA ports are mainly found on professional-grade lasers rather than entry-level units.

Safety Precautions

An interlock switch is crucial for powerful lasers, serving as an emergency shutoff in case of malfunction. High-power units often include a key-lock switch to restrict use to authorized personnel only.

Laser Safety Regulations

Because laser beams concentrate light energy into a very small area, direct exposure can cause severe damage to the eyes. When the beam is deflected—as it usually is in compact show laser systems equipped with scanning units—the risk is significantly reduced.

Lasers and devices containing lasers are classified into safety categories according to ANSI Z136.1 standards. Most compact show lasers on the market, including those sold by us, fall into Class 3a or 3b. These devices require proper authorization and safety measures. For public events in the United States, a certified Laser Safety Officer (LSO) must be designated, following OSHA regulations and ANSI guidelines.

For installations in public spaces (nightclubs, event halls, theatres, etc.), systems must comply with inspection and approval from local authorities. Operators must follow U.S. laser safety laws and regulations issued by the Occupational Safety and Health Administration (OSHA) and the Food and Drug Administration (FDA) Center for Devices and Radiological Health (CDRH).
