The acronym LASER stands for Light Amplification by Stimulated Emission of Radiation

Modern lasers do not amplify light but oscillate waves to organize them precisely

Materials in lasers provide energy boost or 'gain' to parts of the electromagnetic spectrum

Stimulated emission involves energizing atoms to emit photons when light passes through

Some lasers use electron-based mediums within a cavity to amplify and organize light

Coherence ensures all light in a laser beam shares identical properties and phases

The most powerful laser is at the European Extreme Light Infrastructure, generating 10 petaWatts

This laser's pulses are brief but incredibly energetic, affecting particles and possibly physics displays

China's upcoming 'Station of Extreme Light' aims to surpass this with 100 petaWatts soon
