What is Laser Technology?
Laser technology refers to the use of lasers to create, amplify, and manipulate light for a wide spectrum of applications. The word laser means light amplification by stimulated emission of radiation. The laser process has changed our world in incredible ways since its invention in 1960. It describes a process where light is produced and controlled to achieve certain characteristics. They are unique because they emit light that is monochromatic, directional, high-intensity, and coherent. They are highly focused and intense beams that combine with different colours and intensities of lasers, which makes optics and laser technology more versatile for a spectrum of precision tasks.

Principles of Laser Technology
Atom and Energy
Atoms are very tiny blocks of everything. They contain electrons that can exist at different energy levels. When an atom absorbs energy, the electron gets into a higher energy state which is known as excitation. When these electrons go back to their lower state, their relation energy is in the form of Photons.
Stimulated Emissions
It is not like another spontaneous emission where protons are emitted randomly, but this emission happens when an incoming proton interacts with an excited atom. Due to the interaction, it causes the atom to release a second photon identical to the first one.
The Optical Cavity
Laser has an optical cavity with mirrors at both ends. The first mirror is fully reflective, whereas the other one is partially transparent. It increases the light by bouncing photons back and forth which creates a high-directional beam of light.
The Gain Medium
It can be solid, liquid, or gas that amplifies light. For example, it contains helium-neon gas, ruby crystals and semiconductor diodes. Hence, the energy is transported to the gain medium with the help of an external source such as an electric current or another light source.
Types of Laser Technology
Gas Lasers
They use gases like helium-neon or carbon dioxide as the gain medium. The CO₂ lasers are very commonly used in industrial cutting and welding.
Solid-State Lasers
These use solid materials such as ruby or Nd: YAG (neodymium-doped yttrium aluminium garnet) as the gain medium. These are widely used in medical and military applications.
Semiconductor Lasers
It is also called laser diodes, these are the smallest and most widely used in consumer electronics, for example, barcode scanners, and optical communication.
Fiber Lasers
Using optical fibres doped with rare earth elements, such as erbium or ytterbium. These lasers are widely applied in industrial and medical fields, because of efficiency and flexibility.
Excimer Lasers
It uses reactive gases and is most commonly used for medical applications such as eye surgery, for instance, LASIK.
Dye Lasers
Organic dyes in liquid form are used as the gain medium. They are tunable, meaning they can produce light across a range of wavelengths.
