All-laser-diode high-power RGB light-show system fits in 10-in. cube

Laserworld USA (Lake Mary, FL) has unveiled a high-power red-green-blue (RGB) laser light-show system based entirely on the use of visible laser diodes, which enables the whole system to fit in a space about 10 in. on a side and draw only 300 W of electrical power. The specified power outputs of the device's lasers are > 2.4 W for red (638 nm), > 3 W for green (520 nm), and > 6 W for blue (450 nm), making the device a CDRH class IV laser. The diode modules were made in Germany.

The system is sealed within a metal box and weighs 55.1 lb.; a detachable remote-control pad allows the user to stand far from the class IV beam.

The 520 nm green wavelength is close to the peak response wavelength of the human eye. The 638 nm red wavelength is toward the short-wavelength end of the red spectral region, where the eye's response is greater (for red); likewise, the 450 nm blue wavelength is at the long-wavelength edge of the blue spectral region where the eye's blue response is greatest.
