CONCEPT:

  • Laser (Light Amplification by the Stimulated Emission of Radiation): A device that stimulates molecules or atoms to emit light of particular wavelengths.
    • This light is then amplified, to produce a very narrow beam of radiation.

EXPLANATION:

  • The full form of LASER is Light amplification by the stimulated emission of radiation
  • So the correct answer is option 1.
