LASER Full Form: What Is LASER And About All Details



What does LASER stand for in full?

LASER Full Form: Light Amplification by Stimulated Emission of Radiation is the full name of LASER.

LASER stands for Light Amplification by Stimulated Emission of Radiation, and it is a sort of electromagnetic machine that can emit light.


These lights are both coherent and dim. Optical amplification is the mechanism used to create them.

LASER Full Form and of History

LASER Full Form

LASER Full Form: Light Amplification by Stimulated Emission of Radiation. The first individual to mention the LASER process was Albert Einstein. Theodore H. Maiman, on the other hand, completed the system in 1960. The LASER was principally inspired by Charles Hard Townes and Arthur Leonard Schawlow’s idea.

LASER principle of operation

A basic laser is made up of a cavity that is designed to reflect visible, infrared, or ultraviolet radiation to reinforce each other. Liquids, solids, or gases may be present in the cavity.

The output wavelength is determined by the material chosen in the cavity. At each end of the cavity, there are mirrors. One of the mirrors is completely reflecting, allowing no light to flow through.


The other mirror is partially reflective, allowing 5% of the light to pass through. Using a technique known as pumping, energy is pumped into the cavity from an external source.

The waves are reflected back and forth between the mirrors. The length of the cavity is such that reflected waves reinforce one another. The electromagnetic waves emerge in harmony at the cavity’s end, thanks to a partially reflective mirror.

The laser’s output is an electric field that is coherent. In a coherent beam of electromagnetic energy, both waves have the same phase and frequency.

Types of LASER

The types of LASERs are listed here, along with their wavelengths and applications.

  • LASER (gas)
  • LASER Semiconductor
  • LASER (liquid or dye)
  • LASER Excimer

LASER Characteristics

The characteristics of laser beams can be divided into four categories:

  • Exceptional Coherence
  • Excellent Monochromatism
  • High Productivity
  • Increased Directivity

These laser features are used in a variety of applications, including optical communication and protection.

LASER Applications

  • DVD, CD, and barcode scanners all employ lasers.
  • Lasers are utilized in a variety of applications, including drilling, cutting, surface treatment, welding, and soldering.
  • Medical items such as dental treatment devices and cosmetic treatment equipment employ lasers.
  • Laser printing equipment makes use of lasers.
  • LASER is a component of nuclear fusion reactors and is utilized in military equipment (anti-missile devices).

Benefits of LASER

  • It is utilized in the realm of communication for information transfer because of its large capacity to support data.
  • Because laser radiation is free of electromagnetic interference, this technique is used in wireless communication systems via free space for both telephony and computer networking.
  • There is extremely little signal leakage with laser radiation.
  • Laser-based fiber optic wires are utilized in fiber optic networks because they are exceedingly light.
  • Lasers are often employed in the medical field to diagnose cancers because they are less dangerous than X-rays. They’re utilized to burn tiny tumors on the eye’s surface as well as the tissue’s surface.

LASER’s Disadvantages

  • Because lasers are expensive, patients who require laser-based therapy choices face a significant financial outlay.
  • Maintaining lasers is costly, resulting in hefty costs for doctors and hospital managers.
  • Lasers, depending on the laser equipment, increase convolution and treatment time.
