The Laser Harp is Jarre's most iconic stage prop, originally debuted in the early 1980s. Unlike a traditional harp, it uses high-powered green laser beams that act as "strings."

: It represents Jarre’s lifelong obsession with the "physicality" of electronic music—trying to make invisible sounds visible and tangible.

: While newer digital instruments exist, the Laser Harp remains Jarre’s signature because of its sheer scale and the precision required to play it without "ghost notes" or sensor errors in a stadium environment.

: The beams are projected upward into the air. When Jarre's hand "breaks" a beam, a sensor (typically a photocell at the base) detects the lack of light and triggers a specific MIDI note via a synthesizer.

: Jarre famously wears specially designed asbestos or Kevlar-lined gloves to protect his hands from the heat of the lasers and to ensure better light reflection back to the sensors. "The Time Machine" Performance

: The song itself was a collaboration with Boys Noize, reflecting the album's theme of connecting electronic music's past (Jarre) with its present and future. Impact and Legacy

For fans, seeing the Laser Harp live is a ritual. During "The Time Machine," it serves as more than just a musical instrument; it is a piece of performance art.
