Laser lights are optical devices centered around a YAG solid-state laser. They utilize krypton lamps to pump an Nd:YAG crystal rod, generating a 1064nm fundamental frequency light, which is then converted to 532nm visible green light through frequency doubling technology. This light is then scanned by a computer-controlled galvanometer to form text or graphics. They are mainly divided into industrial and entertainment categories, and are widely used in stage performances, outdoor advertising, and landmark projection.
The core technologies include a high-speed galvanometer system, a semiconductor laser, and a cooling system. They support multiple control modes such as DMX512 and voice control, and have built-in safety mechanisms such as automatic light shut-off in case of no signal. Products include monochrome, full-color, and animated models, with power ranging from 50mW to 20W, and wavelengths covering red (635-650nm), green (532nm), and blue (457nm). Outdoor models are adaptable to environments from -40℃ to 50℃, integrate a temperature and humidity protection system, are compatible with the ILDA standard interface, and support real-time programming and large-scale performance needs.
