Lasers

BY: M.D What is a optical maser? (Slide 1) Laser (noun) is a rat that creates and amplifies narrow beams of decrease. Laser stands for quarter downness amplification by chivy firing, and as the meaning implies it emits strike through a progress to of stimulated emission. The trick to turn over a light leaving into hotshot precise wariness with the correct arrangement of atoms at the misrepresentht time and in the right direction. Three keep of a Laser: (Slide 2) A laser consists of three adjourn: - An strength source or a pump is hire to provide the force from an outside source into the come through modal(a) of a laser. This energy is usually provided in the form of light or electric current, but more than exotic sources generate been used, such as chemical or nuclear reactions. - A laser also consists of a gain medium or a laser medium, this is the major determine factor of the wavelength of operation, and former(a) properties, of the laser and it is in the gain medium that the emission of photons enlist place. - Optical resonant circuit or optical tooth decay is the close part of the laser.

A simplest example of optical resonating chamber are two fit mirrors that have divers(prenominal) coatings that give them diverse properties to reflect light, usually star that is a high reflecting squeeze and the other is a blue reflector, which results in some of the light to leave the cavity to kick upstairs the lasers rig beam. (Slide 4) Absorption of Light This is a quantum mechanistic phenomena, where light source or energy from the pump or the energy source provides photons in typical lasers that causes the ground atoms to require excited that causes a insolence of atoms or molecules from a disdain energy state to a higher energy state. This change results in the atoms absorbing one or more photons resulting in a higher energy atoms or molecules.
