How do lasers help us?
In the real world, lasers correct people's eyesight, remove tattoos and operate CD players . ... Lasers (Light Amplification by the Stimulated Emission of Radiation) are made up of light waves that are in phase with each other – all travelling in the same direction and usually all one wavelength.
What are positive impacts of lasers?
While lasers are used to cut or remove tissue, relieve pain, reduce inflammation and edema , promote wounds, prevent tissue damage, and heal deeper tissues and nerves in medicine, they stimulate and enhance cell and tissue function. The effects of lasers are confined to the special set of wavelengths.
Why is laser important?
Laser technology is very important in the modern world because it is used in many fields, most notably measurement, where it is used to give high accuracy results in measuring small and large distances . Laser technology is also used for the purposes of generating heat in industrial cutting processes.
What is bad about laser?
Improperly used laser devices are potentially dangerous . Effects can range from mild skin burns to irreversible injury to the skin and eye. The biological damage caused by lasers is produced through thermal, acoustical and photochemical processes.
What is the disadvantage of laser treatment?
some of the other risks include blistering, discolouration, redness, and scarring . There's also the possibility that your hair could grow back and may require yearly treatments to keep new hair growth at bay. Risk of pigmentation: There is a chance of increase or decreased pigmentation in the treated areas.
What is laser and its uses?

What is the basic principle of laser?
A laser emits a beam of electromagnetic radiation that is always monochromatic, collimated and coherent in nature. Lasers consist of three main components: a lasing medium (solid, liquid or gas), a stimulating energy source (pump) and an optical resonator; and have a wide variety of uses in clinical medicine.
