All of these laser types share a basic set of components. Now we will discuss in detail about characteristics of laser light.

A laser is a device that emits a beam of coherent light through an optical amplification process.

What is Laser? Meaning, Uses and Application of Laser. The conventional light sources such as electric bulb or tube light does not emit highly directional and coherent light whereas lasers produce highly directional monochromatic coherent and polarized light beam. In this the clouded lens is removed with the aid of a femtosecond laser and subsequently replaced with an artificial lens. CO lasers emit in the 5 to 6 µm spectral range.

Lasers are used for recording and retrieving information. For example many people were first introduced to lasers by concerts in the early 1970s that incorporated laser light. Laser light has extra-ordinary properties which are not present in the ordinary light sources like sun and incandescent lamp.

They also help to make parts for computers and other electronics. Lasers found their first use in the 1970s in local grocery stores in the product scanner. Lasers deliver coherent monochromatic well-controlled and precisely directed light beams.

Lasers are used in the therapeutic area for example for cutting through or removing layers of tissue such as in the treatment of cataracts. Laser light is highly directional light of the laser can be sharply focused. The emission generally covers an extremely limited range of visible infrared or ultraviolet wavelengths.

Laser light is highly monochromatic. The light emitted by the He-Ne laser is extremely monochromatic unidirectional spatially coherent and aligned to be parallel to the body of the laser. There are many types of lasers including gas lasers fiber lasers solid state lasers dye lasers diode lasers and excimer lasers.

Laser a device that stimulates atoms or molecules to emit light at particular wavelengths and amplifies that light typically producing a very narrow beam of radiation. This shorter wavelength mid-infrared output offers two important advantages for some applications as compared to CO 2 lasers. Laser - Laser - Laser applications.

Its light is highly coherent. The next major accomplishment for laser technology was the CD player. Today uses span from hospitals to battlefields to electronics to factories.

We also find them in laser printers bar code scanners and DVD players. Here are some examples. They are used in communications and in carrying TV and internet signals.

Tungsten light spread over a continuous spectrum gives no basis for comparison. A similar technology is the carbon monoxide CO laser which was originally developed in the 1960s but only made truly practical for industrial use in 2015. Although lasers make poor choices for general-purpose illumination they are ideal for concentrating light in space time or particular wavelengths.

Lasers are also used in instruments called spectrometers. Red HeNe lasers have a number of industrial. Light of the laser is highly monochromatic.
