It is possible to create a gas laser when an electric current is discharged through a gas to generate coherent light. GAS LASERS, which operate on the premise of transferring electric energy into laser light output, were the world’s first continuously operating lasers as a result of the cheap cost and excellent coherence of He-Ne lasers, they are primarily used in optical research and educational labs. Carbon dioxide (CO2) lasers, which have the potential of emitting hundreds of watts in a single spatial mode, are utilised in the manufacturing industry for cutting and welding.
Chemical Lasers are a kind of laser that uses chemicals to produce light.
Chemical lasers are made possible by the release of a huge quantity of energy fast through chemical processes. Because of its high power energy release propensity, it has several specific military applications. In industrial settings where chemical lasers are fueled by streams of gases, the technology has shown to be effective.
Excimer lasers are a kind of laser.
Excimers are molecules that may exist with one atom in an excited electronic state, and they are a kind of molecule. Today’s models of this laser technology make use of a specific gas laser that is pushed by an electric discharge, with the lasing medium being either an excimer or an exciplex. These lasers operate at a wavelength that is close to that of ultraviolet light and have a wide range of applications, including photolithography and LASIK (laser in-situ keratomileusis) vision correction.

Solid-state lasers (also known as SSLs).
When in a solid-state, the laser gain medium is solid, as opposed to liquid in dye lasers and gas in gas lasers when in a liquid state. It makes use of a glass rod or a crystalline rod that has been “doped” with ions to produce energy states to work. Solid-state lasers are mostly used in the creation of defensive weaponry.
Fibre Lasers (also known as fibre lasers) Using a single-mode optical fibre to direct the total internal reflection in solid-state lasers or laser amplifiers, is referred to as Fiber Laser technology. A considerable cooling effect is produced by light moving through long gain zones as a consequence of its long wavelength. Because of the large surface area to volume ratio, it is very effective at cooling. Fibre Lasers are widely used in industry for a variety of tasks such as cutting, marking, welding, hardening, and cladding.
Lasers made of photonic crystals
They are nanostructured lasers that offer the mode confinement and density of optical state (DOS) structure essential for the feedback to occur.
Dye lasers are the seventh kind of laser.
Another form of laser is a dye laser, which uses an organic dye as the gain medium to produce light. These lasers provide a wide range of tuning options (wavelength can be altered). Even though these lasers are solid-state lasers, scientists have proven emission in dispersive oscillator tenability by adding solid-state dye gain medium into the laser. They are employed in a variety of applications including astronomy (the laser-guided study of stars), spectroscopy, isotope separation, and a variety of other fields.
Free-Electron Lasers are the eighth kind of laser.
While Free Electrons, as the name implies, is not confined to specific atomic or molecular states, they do so by using a relativistic electron beam as the lasing medium instead. These lasers have a broad variety of wavelengths, ranging from microwaves to infrared to soft X-rays and everything in between. Because of their independence, they have the widest possible variety of wavelengths to choose from.
