What is a laser?
laser is an acronym for for “Light Amplification by Stimulated Emission of Radiation.” a laser is a special form of light source, where the wavelength is consistent. light from a laser doesn't spread out in all direction and focuses on a small area, the light is intense and concentrated thus allowing lasers to cut through steel when cutting or perform precise duty such as eye surgeries.

How is a laser created
when a laser is created, energy such as a electric current is passed through a medium gas for example krypton,argon,and argon-fluoride. when a light shoots through the material, a specific wavelength is amplified. The wavelength that is amplified depends on the medium material used, different types of gases produce different colored lasers that is fitted to different applications.
Specifically, when the energy such as an electric current passes through the medium gas. The atoms receives energy, when the atoms changes back to the usual state the energy is released as electromagnetic radiation which generates a light rays. When a lot of light is emitted and discharged it creates a stream of high energy laser beam.
Typically a laser is generated using a tube filled with medium material and mirrors on both sides to increase the times the light amplified, on one of the mirror is a hole for the laser beam to exit.

Behavior of laser
Laser behaves much like regular light, it will reflect when in contact with a reflective surface such as a mirror. A laser will refract when in contact with liquid mediums like water. Additionally, because of the high energy level of the laser, it will have a different reaction when hitting objects that is opaque. Depending on the laser used the laser might burn the material or create a cut.Argon ,and Krypton medium that create thermal lasers will convert light into heat and apply heat on the other object. Yttrium aluminium garnet ,and Argon Fluoride medium that create Photo Disruptive lasers that can achieve precise cut on tissues.
When using thermal lasers to vaporize a tissue, the heat is distributed on to the cells until they swell and burst.
