Electronic Laser Applications in Engineering Laboratory and Medical Devices: Review

Abstract

This review deals with Laser engineering technology which is considered one of the advanced sciences that is included in many engineering applications. For Example, the use of lasers in engineering, medical, communications, scientific, engineering and military research. Any laser user, regardless of their specialization, needs to understand the principle of laser work, i.e. what is known as laser physics. A laser is a device that converts energy from different sources into electromagnetic radiation. This is a simple definition to start the topic and clarify the idea of laser work, as we eventually get an electromagnetic beam (light) that has many properties that distinguish it from any light source. The name LASER came from the initial letters of the idea of laser work, which is Light Amplification by Stimulated Emission of Radiation. It means the amplification of light by the inductive emission of electromagnetic radiation. The existence of the laser was predicted by Albert Einstein in 1917, where he laid the theoretical basis for the stimulated emission process. The first laser device was designed in 1960 by the scientist T.H. Maiman using a sapphire crystal is known as a ruby laser.
