Let Start. laser full form

LASER Full Form: Light Amplification by Stimulated Emission of Radiation. 

The LASER full form is Light Amplification by Stimulated Emission of Radiation. It is a type of electromagnetic machine that emits light by electromagnetic radiation. This type of method of producing light is called Optical Amplification.

Such types of lights are both coherent and very weak. The LASER is used for the transmission of information in the communication field. 

History Of LASER: 

The first person to speak about LASER was Albert Einstein. He was a famous scientist in different fields. The system of LASER was developed by Theodore H. Maiman in 1960, later Charles Hard Townes and Arthur Leonard Schawlow introduced the concept and build the LASER. 

What is LASER Principle? 

A simple laser consists of a chamber identified because the cavity that’s built to reflect waves of visible, infrared, or ultraviolet to strengthen each other. The cavity may include liquids, solids, or gases. the fabric selection within the cavity decides the output wavelength. Mirrors are located opposite to each other at either end of the cavity. one among the mirrors is fully reflective in order that none of the sunshine will pass into them. the opposite mirror is reflective partially, allowing 5 percent of the sunshine to go through it. Energy is pumped into the cavity from an external source through a technique called pumping.

The waves in between the mirrors are reflected back and forth. The length of the cavity is such waves that are reflected reinforce one another. At the tip of the cavity, with a partially reflective mirror, the electromagnetic waves emerge consonant with each other. The laser output may be a coherent, field of force. Both waves have an equivalent phase and frequency during a coherent beam of electromagnetic energy.

List of LASER types.

The list of LASER types are given below depending upon their wavelengths and application. They are five different types of LASER that are available. 

• Gas LASER
• Semiconductor LASER
• Chemical LASER
• Liquid or Dye LASER
• Excimer LASER

 GAS LASER:

A gas laser is a type of laser in which to produce coherent light, an electrical current is discharged through a gas. . The gas laser was the primary continuous-light laser in history and also, the first gas laser to work on the principle of converting electrical power to a laser light output.

Examples of Gas LASER are nitrogen lasers and copper vapour lasers.

 Types of GAS LASER:

• Carbon Dioxide LASER
• Carbon Monoxide LASER
• Helium-Neon LASER
• Nitrogen LASER
• TEA LASER

Advantages of Gas LASER.

• The active material volume is high.
• The active material is inexpensive.
• From the cavity, heat can be removed quickly. 
• Impossible to damage the active material.

Semiconductor LASER.

A semiconductor laser (LD) may be a machine that produces laser oscillation by flowing an electrical current to the semiconductor. The mechanism of sunshine emission is that the same as a LED. When the 2 meet at the junction, an electron drops into a hole, and lightweight is emitted at the time.

Types of Semiconductor LASER.

There are three types of Semiconductor LASER that are given below. 

• Fabry-Perot semiconductor laser
• DFB semiconductor laser
• FBG wavelength stabilized semiconductor laser

Advantages of Semiconductor LASER.

• Small volume
• Lightweight
• Good Readability
• Long service life, and
• Low power consumption

 Uses of Semiconductor LASER.

Semiconductor LASER uses for different purposes, which are given below.

• Optical communications
• Optical data storage
• Metrology
• Spectroscopy
• Material Processing
• Pumping of other lasers
• Medical treatments

Chemical LASER:

A chemical laser may be a laser that obtains its energy from a chemical process. Chemical lasers can reach continuous-wave output with power getting to megawatt levels. they’re utilized in industry for cutting and drilling. The chemical LASER was invented by researchers at The Aerospace Corporation in El Segundo, California. 

These are the common examples of chemical lasers such as oxygen-iodine laser (COIL), all gas-phase iodine laser (AGIL), and hydrogen fluoride (HF), and deuterium fluoride (DF) lasers. Chemical LASERs are used in industry for cutting and drilling.

Liquid or Dye LASER:

A dye laser is a type of laser that uses an organic dye due to the lasing medium, usually a liquid solution. The gases and most solid-state lasing media, a dye can usually be used for a wider range of wavelengths. SSDL uses dye-doped organic matrices due to the gain medium.

Liquid lasers are almost like solid-state lasers, but they use a cooling liquid that flows through channels integrated into the solid-state laser material. The system promised to be both compact and relatively lightweight, just what DARPA wanted to suit a 150-kW laser into a fighter jet

Excimer LASER:

Some time excimer LASER is correctly called exciplex laser. It is a form of ultraviolet LASER that is used for the production of micro-electric devices. Excimer lasers are utilized in scientific laboratories to pump dye lasers, also on generating higher harmonics to succeed in the vacuum-ultraviolet range.

• STAR S4 IR Excimer Laser System.
• Nidek EC-5000 Excimer Laser System.
• Allegretto WAVE Eye‑Q Excimer Laser System.
• MEDITEC MEL 80 Excimer Laser System.
• LADARVIsion 4000 Excimer Laser System

These are some top FDA-approved excimer lasers used by surgeons around the countries.

Properties of LASER:

Properties of LASER may be classified into four types that are given below.

• Superior Coherence
• Superior Monochromatism
• High Output
• Superior Directivity

The most unique property in the laser is coherence. It grows from the stimulated emission process that provides amplification. Since a standard stimulus triggers the emission events which give the amplified light, the emitted photons are “in step” and have a particular phase reference to one another.

Using these properties of LASER for different purposes like optical communication and protection. 

Application of LASER:

• Uses in DVD, CD, and Barcode Scanners.
• Uses in different purpose devices like drilling, cutting, surface treatment, welding, and soldering equipment.
• LASERs are used in ental treatment devices, cosmetic treatment equipment which is comes under the medical fields. 
• Utilize in the LASER printing machine.
• Used in military equipment and integral component of the nuclear fusion reactor.
• Laser Range Finding.
• Information Processing 
• Bar Code Readers.
• Laser Surgery.
• Holographic Imaging.
• Laser Spectroscopy.
• Laser Material Processing
• Surface modification
• Welding, cladding, soldering, marketing. 

• The main advantage of LASER is, used for the transmission of information in the communication field.
• This principle of no interference of electromagnetic is employed in wireless communication systems via free space for both telecommunication and computer networking since the laser radiation is freed from this interference.
• Laser radiation includes little or no leakage of the signals.
• In fiber optic systems laser-based fiber optic wires are used because they’re very lightweight.
• Lasers are commonly used for the diagnosis of cancers within the medical sector because they’re less harmful compared with X-rays. they’re wont to burn small tumors on the surface of the attention.

• Lasers are expensive, and thus, those patients who need laser-based treatment options are much expenditure.
• Lasers are expensive to take care of it, and thus cause high costs to doctors and hospital administrators.
• Lasers elevate the convolution and therefore the treatment period supported laser equipment.

Some interesting facts about the LASER full form:

• The green LASER is powerful and fastest compared to other colors of LASER.
• High powerful LASER is dangerous for humans, especially for human eyes.
• You can guess the reach of a strong laser from the very fact that it can easily reach the moon’s surface.
• Today many countries are trying to making laser weapons, among them, China is listed top in the countries names.
