Laser vs. Light — What's the Difference?

By Tayyaba Rehman — Updated on September 20, 2023
Laser is a focused beam of light where the photons are coherent and travel in the same direction. Light is a broad term for electromagnetic radiation that includes visible, infrared, and ultraviolet forms, and is often diffuse and incoherent.

Key Differences

A laser is a concentrated beam of light that is coherent and usually monochromatic. Light, on the other hand, is a general term that describes the various forms of electromagnetic radiation that can be detected by the human eye and other sensors.
The term "laser" stands for "Light Amplification by Stimulated Emission of Radiation," and it generates light that is more focused and intense. Light, in a broader sense, can be natural or artificial, and includes the spectrum of colors we can and can't see.
Laser light has many applications because of its coherence and focus, including in medicine, communications, and manufacturing. Light, in a general sense, is essential for vision, photosynthesis in plants, and as a source of energy and warmth.
In a laser, the emitted light is usually of a single wavelength, making it monochromatic. Light, conversely, often exists as a mixture of multiple wavelengths, which may or may not be visible to the human eye, depending on its spectral composition.

Light

Electromagnetic radiation detectable by the human eye.

Light

Light or visible light is electromagnetic radiation within the portion of the electromagnetic spectrum that is perceived by the human eye. Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm), between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths).

Laser

Laser

Any of several devices that emit highly amplified and coherent radiation of one or more discrete wavelengths. One of the most common lasers makes use of atoms in a metastable energy state, which, as they decay to a lower energy level, stimulate others to decay, resulting in a cascade of emitted radiation.
