The Correct Option is A

Solution and Explanation

LASER stands for Light Amplification by Stimulated Emission of Radiation. It is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The principle was first described by Albert Einstein in 1917, and the first laser was developed in 1960 by Theodore Maiman.
Hence, the correct answer is Light Amplification by Stimulated Emission of Radiation.
