How does a laser harp work?
A laser harp is an electronic musical user interface and laser lighting display. It projects several laser beams played by the musician by blocking them to produce sounds, visually reminiscent of a harp. It was popularised by Jean-Michel Jarre, and has been a high-profile feature of almost all his concerts since 1981.

What happens if you point a laser at the moon?
The laser pointer on the moon is basically the same. Each photon travels to the moon at the speed of light, but the image of a dot that they form on the surface moves 20 times faster. No physical laws are broken, because nothing physical is actually traveling faster than light.
What are the 4 types of lasers?
What type of laser is the smallest?
Surface-plasmon lasers
Surface-plasmon lasers could enable a new generation of computers based on nanophotonics. Researchers have demonstrated the smallest laser ever, consisting of a nanoparticle just 44 nanometers across. The device is dubbed a “spaser” because it generates a form of radiation called surface plasmons.
