LASER Full Form

LASER full form is Light Amplification by Stimulated Emission of Radiation. It is considered an electronic device that emits light. This process is based on electromagnetic radiation. This electromagnetic radiation is carried out through the process known as optical amplification. In simple words, a laser is a tool that emits light through the process of ‘optical amplification’ that is based on the mechanism of an increased releasing of electromagnetic radiation. LASER is an electromagnetic machine from which the light is emitted in the form of Electromagnetic Radiation. These lights are both coherent and faint in nature. 

What is the Full Form of LASER?

LASER's full form is Light Amplification by Stimulated Emission of Radiation. It is a device that enhances atoms or molecules in a particular way such that the light of some specific wavelengths is generated. In general, it covers a restricted range of visible, infrared, or ultraviolet wavelengths.

Various types of devices have lasers and the characteristics have been produced over the years. The rays produced by these gadgets have been proven to be beneficial for humans, therefore they have used these in several different ways.

History of LASER

Albert Einstein gave the first implication of the laser in 1917. However, a scientist named Theodore H. Maiman invented the first LASER device in 1960. This accomplishment was achieved at the Hughes laboratory and the theories of Charles Hard Townes and Arthur Leonard Schawlow helped to make the invention possible. Since then, there have been improvements and updates in the LASER industry regularly.

Understanding the Principle of LASER

LASER can be regarded as a technological evolution but few know about its working principle. The guiding force behind the smooth functioning of a laser is quantum mechanic rules. Scientist Albert Einstein has discovered two methods of light emission in a laser. In this system, the photon particles are emitted profusely which in a way stimulates atoms, and electrons of the atoms become activated thereby shifting from a high level of energy. With the movement of electrons, energy at a bombastic level is produced that ultimately emits an arrow beam.

Well, it won’t be wrong to say that laser light’s principle remains highly dependent on the fluctuating energy level of an atom's electron. The continuous outpouring of photon rays helps in transferring energy to the electrons lying in a stable state. In this situation, energy-absorbing electrons emit beam rays of light that are what we call laser rays.

What are Different Types of LASERs?

Over the years, people have recognized the significance of lasers. This has, in turn, encouraged them to manufacture various types of LASERs. Given below are some of the different types of lasers available in the market that are commonly used for carrying out different workins. Each of the LASER has its distinct features and applications. Different types of LASERs are:

1. Solid State LASER
2. Gas LASER
3. Dye or Liquid LASER
4. Excimer LASER
5. Chemical LASER
6. Semiconductor LASER

Characteristics of LASER

There are various characteristics of a device that make it different from other conventional light sources. A few of the most significant characteristics of LASER are:

1. The beam of light produced by LASER is generally narrower in appearance than that provided by other sources.
2. The lesser or negligible diversion of the laser beams makes it effective to be used in remote sensing, surveying, etc.
3. The deviation of the light depends on the distance between the two walls and the extent of diffraction witnessed by the beam.

What Are the Applications of LASER?

Light Amplification by Stimulated Emission of Radiation (LASER full form) is ineffective for wide lighting but they are beneficial for focusing light in space, time, or specific wavelengths. Earlier, many people were exposed to lasers through laser light shows at concerts. In the early 1970s, moving laser beams of different colors showcased shifting patterns on planetarium domes, music hall ceilings, or outdoor clouds. Some of the applications of the Light Amplification by Stimulated Emission of Radiation are:

1. Used for transmission and processing of the information
2. Delivering a definite amount of energy
3. Application in the imaging industry

Uses of Lasers

The use of laser rays has a wide range of applications such as for performing delicate surgery, heavy-duty welding, commonplace alignment of suspended ceilings, scientific measurements of atomic characteristics and structure, and many more day-to-day life purposes.

Use of Laser Rays in War

In wars, laser rays are used to destroy the enemy’s weapons. Different types of lasers are used to detect and destroy the missiles. Different types of lasers such as Free-electron lasers, x-ray lasers, xenon fluoride lasers, etc. are used to detect missiles on Earth. In current days, laser rays are being used for technological aspects such as laser rifles, laser pistols, laser bombs, etc.

Moreover, X-ray lasers are used to provide the required amount of energy needed to shatter nuclear bombs. X-ray lasers are being developed at a place called Nevada, in the USA. With the aid of a laser distance-measuring device, the distance of enemy tanks, missiles, and other targets on the ground or in the sky is measured. Apart from this, laser rays are also used in the area of communication in computers to detect pollution levels, in holography, in television, in meteorology, in finding distances of various celestial bodies from the earth, in detecting earthquakes, leveling roads, etc.

Use of Laser Rays in Medical Science

In the medical science field, the laser, the full form of which is Light Amplification by Stimulated Emission of Radiation, is used in surgery. It is treated with an instrument called a laser retinal-photocoagulation when the retina in the eye has moved out of place. Laser rays such as Ruby laser or argon laser rays are used in this surgery device. The healing of wounds in the corner of the eye is also conducted by laser rays. Laser rays are also used to curb or prevent tooth diseases. Along With this, they are also used in the treatment of cancer, tumors, stomach diseases, skin treatment, etc.

Use of LASER to Join Metals

Various metals are joined in the aircraft using laser technology. Laer rays called Ruby Lancer Neodymium Yag lasers are used to join metals. 

Use of LASER for Printing

Different types of lasers such as helium-neon lasers are also used in printing technology.

With the aid of a carbon dioxide laser, the printing ink dries up instantly. Marble rocks etc. are also broken down by laser rays, tunnels are also constructed using this technique.

Use of LASER Rays in Industries

In industries, due to the presence of high energy in laser rays, it is used to make holes in various metals and to cut metals. The hole made with the laser is so fine that it is not visible even with the bare eyes. Apart from this, Light Amplification by Stimulated Emission of Radiation (LASER full form) rays is also used in many fields of science and technological invention.

Benefits and Limitations of LASER

LASER, the full form of which is Light Amplification by the Stimulated Emission of Radiation, is considered infrared radiation used across various industries. This gadget emits atoms and uses quantum physics to deliver light. To understand it's working properly, it's vital to explore some of its benefits and limitations.

Benefits:

• Lasers produce electro-attractive obstruction which proves significant for applications whereby security is vital. For eg, the security system makes use of a laser.
• It is widely adopted in the medical field because of its emitting non-harmful radiation, unlike X-beams. Lasers are often used to remove small tumors found on the eye surface.
• For its swift and smooth data conveying limit, the laser is adopted in spaces where large-scale data transferring is conducted.

Limitations:

• One of the biggest limitations of utilizing a laser in any industry is its high cost. Hence, it is generally used in high-specialty treatments.
• When using a laser for cutting activity, a slight change in the temperature can result in the staining of metals.
• It might prove dangerous for those coming in regular contact with the laser rays
