LASER Full Form

Full form of LASER is Light Amplification by Stimulated Emission of Radiation, which causes specific atoms or molecules to emit light with a particular wavelength. A small amount of UV light, visible or infrared light is absorbed by lasers.

Optical disc, barcode scanners, laser printers, DNA sequencing equipment, fiber optics, laser surgery, and skin treatments, cutting and welding materials, manufacturing laser chip (photolithography), and military and law enforcement equipment for marking targets and measuring range and speed all use lasers.

History of LASER:

• T. H. Maiman of Hughes Laboratory invented the first​ laser in 1960.
• Albert Einstein laid the theoretical ​ groundwork in 1917.
• Based on Arthur Leonard Schawlow and Charles Hard Townes’ theory, it was developed.

How LASER Works:

• The gain medium of the laser, which can be a solid, liquid, or gas, takes in energy from an outside source.
• The gain medium’s atoms, ions, or molecules are excited by this energy, which causes them to move to a higher energy level.
• A spontaneous transition back to ​ lower energy is possible ​ for iron atoms or molecules ​that are in an excited state.
• They discharge photons (light) with particular wavelengths and directional characteristics during this transition. Randomness governs the phases and directions of spontaneous emission.
• Stimulated emission can happen when an excited atom, ion, or molecule is near a photon that has the same energy and direction as the photon that was released.
• A second photon with the same energy, phase, and direction as the incoming photon is released by the excited particle as a result of the interaction between the incoming photon and the excited particle.
• As a result, more photons with the same characteristics are created, Amplifying the original light.

Application of LASER:

• Light Amplification by Stimulated Emission of Radiation is a key component that is used in nuclear fusion reactors.
• Used in a variety of tools for cutting, drilling, treating the surface, soldering, and welding.
• Medical equipment that is used in dental and cosmetic procedures.
• Printers with lasers were used.
• Used in military equipment, including anti-missile systems.
• Light Amplification by Stimulated Emission of Radiation​ or LASER is a component of CD ROMs and DVDs.
• In a barcode scanning technology, Light Amplification by Stimulated Emission of Radiation or LASER is used.

Advantages of LASER:

• Excellent directionality is a feature of LASER beams. so that they can keep their focus while traveling great distances.
• Usually monochromatic, laser light has one color. Research in science and medical treatments both benefit from this quality.
• Highly coherent light is produced by lasers. Telecommunications can benefit from this distinguishing trait.
• Without making direct contact, materials can respond to lasers. Non-destructive testing, medical diagnostics, and material handling all benefit from this property.

Disadvantages of LASER:

• Development, acquisition, and upkeep of laser technology can be costly.
• There is a lot of heat produced by LASER. In order to do this, it needs powerful cooling systems and also power.
• The skin and eyes are damaged by LASER beams.
• It is a very complicated process to use LASER​ technology.

FAQs on LASER:

Q1. What is the full form of LASER?

Ans: The full form of LASER is Light Amplification by Stimulated Emission of Radiation.

Q2. Who invented LASER?

Ans: T. H. Maiman of Hughes Laboratory invented the first​ laser in 1960.

Q3. What are the uses of LASER?

Ans: Optical disc, barcode scanners, laser printers, DNA sequencing equipment, fiber optics, laser surgery and skin treatments, cutting and welding materials, manufacturing laser chip (photolithography), and military and law enforcement equipment for marking targets and measuring range and speed all use lasers.

Q4. How LASER works?

Ans: Lasers emit a focused beam of light with very similar wavelengths across the board. The light waves from the laser move in tandem with one another and have their peaks in phase.

Q5. What are the uses of LASER in the medical field?

Ans: Usually monochromatic, laser light has one color. Research in science and medical treatments both benefit from this quality.
