Lasers emit light through a process of optical amplification based on the stimulated emission of electromagnetic radiation, producing a coherent beam with a narrow spectrum of wavelengths. They have diverse applications ranging from medical procedures and telecommunications to manufacturing and scientific research.

Lasers

Optical amplification is a process used in fiber optic communications to boost the strength of light signals without converting them to electrical signals, thereby enhancing transmission distances and data rates. It is crucial for long-haul communication systems as it compensates for signal loss due to fiber attenuation and other impairments.

optical amplification

Stimulated emission is a process where an incoming photon induces an excited electron to drop to a lower energy level, emitting a second photon with the same phase, frequency, polarization, and direction as the incoming photon. This principle is fundamental to the operation of lasers, where it leads to the amplification of light.

stimulated emission

Electromagnetic radiation is a form of energy that travels through space at the speed of light, encompassing a wide range of wavelengths and frequencies known as the electromagnetic spectrum. It includes visible light, radio waves, X-rays, and more, each with unique properties and applications in fields like communication, medicine, and astronomy.
