Jean Michel Jarre plays the laser harp

A laser harp is a user interface to control an electronic musical instrument and a laser show that consists of multiple laser beams . These are interrupted with the hands (analogous to the plucking of harp strings ) in order to give signals for the generation of tones.

The first working laser harp is said to have been manufactured by Bernard Szajner in 1980 (patent: FR2502823 (A1) Date de priorité: 27th Mars 1981). The instrument became known through concerts by Jean Michel Jarre .

A laser harp generally has a single laser whose beam is split into a parallel or fan-shaped array of beams. If a beam is interrupted, this is registered by photoresistors or photodiodes , which are connected to an electronic assembly that activates the corresponding sound. The actual sound is usually generated with a synthesizer , sampler or computer .
