LASER: Light Amplification by Stimulated Emission of Radiation

These electromagnetic radiations or lights can be both coherent and weaker. This is called optical amplification.

Albert Einstein was the first to describe the LASER process. Theodore H. Maimane was the first to fully develop the laser system. Arthur Leonard Schawlow and Charles Hard were the first to propose LASER, which is the basis for the system.

LASER principles

It is a method that amplifies light by stimulating emission of radiation. It has certain working principles.

A simple laser includes a cavity that can reflect waves of ultraviolet, visible, or infrared light to strengthen one another. It is also called a chamber in simple lasers.

The cavity can be filled with solids, liquids, or gases. This material selection will determine the output wavelength later. Mirrors can be found at the bottom of the cavity. One of these mirrors has a whole reflective coating that blocks light waves from passing through it.

A mirror in the cavity that is reflective allows for 5 percent of the light to pass through it. A pumping technique is used to inject energy into the cavity from an external source.

These mirrors are used to reflect waves back and forth. The cavity’s length is maintained so that waves that are reflected can strengthen each other.

An end mirror is placed at the cavity’s end so that the electromagnetic waves emerge in harmony.

LASER produces a coherent electric field. Both waves are similar in frequency and phase when they travel on a coherent beam of electromagnetic energies.

The benefits of LASER

The LASER system is an important innovation. Here are some of its most well-known benefits.

  • Because of its high capacity for supporting information, the LASER system can be used to transmit information in the communication field.
  • The Laser radiations are virtually indestructible.
  • Because LASERS have a lower risk of cancer than X-rays, LASERS can be used to diagnose and treat medical problems.
  • LASERS can be used to remove small cancerous tumours on the cornea and tissue.
  • The LASER principle of no interference with electromagnetic is used in wireless communications systems that use free space for computer networking and telecommunication. This is because the laser radiation is not contaminated.
  • Because they are light-weight in fibre optic systems, laser-based fibre optic wires can be used.

Cons of LASER

While the LASER system has many advantages, it also has its drawbacks.

  • Lasers increase the convolution and treatment time using laser equipment
  • Lasers are expensive, so patients who require this laser-based treatment must be prepared to spend a lot.
  • The LASER system can be expensive and hard to maintain, so it is costly for doctors and hospital administrators.

Laser: Interesting facts

  • The green laser is the strongest and farthest visible.
  • A powerful laser can be dangerous for humans. It is especially dangerous for the eyes.
  • The fact that a powerful laser can reach the moon’s surface easily is enough to show its reach.
  • Laser weapons are being made by many countries today, with China leading the pack.

Laser FAQs

What are the differences between LASER types?

The wavelengths and the applications of lasers will determine which type you choose. These are the different types of LASER.

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

What are the different properties of LASER?

Laser properties such as optical communication and protection can make it useful in many areas. These properties are known as laser beam characteristics. They can be broken down into four groups. These are the LASER properties.

  • Superior Monochromatic
  • Superior coherence
  • Superior directivity
  • High Output

What are the uses of LASER?

There are many ways to use LASER, such as:

  • Lasers are used in medical devices such as cosmetic treatment equipment and dental treatment devices.
  • Lasers are used in CDs, Barcode scanners, and DVDs.
  • There are many types of devices, including surface treatment, drilling, cutting, welding and soldering equipment. Use LASERS.
  • The LASER method is also used for printing devices.
  • The LASER system is used to equip military devices such as anti-missile systems as an integral part of Nuclear Fusion Reactors.
