Laser light is a form of electromagnetic radiation that is coherent, monochromatic, and highly directional, making it distinct from ordinary light sources. Its unique properties arise from the stimulated emission of photons in a laser medium, allowing for precise applications in fields such as medicine, telecommunications, and manufacturing.

Coherent light is a type of light in which the waves maintain a constant phase relationship, allowing them to interfere constructively or destructively. This property is essential for applications like lasers, holography, and optical communications, where precise control over light is required.

A laser medium is the material used in a laser that amplifies light by stimulated emission, determining the laser's wavelength and efficiency. It can be a solid, liquid, gas, or semiconductor, and its properties are crucial for the laser's application in various fields such as medicine, communications, and manufacturing.
