Let me explain about a device, which can emit lights on Facts about Lasers. This light is generated using the optical amplification. Theodore H. Maiman worked at Hughes Research Laboratories to create the first laser in 1960. Laser earns a special status due to the distinctive source of light. It allows the user to point the laser at a very tight spot. That is why laser is also applied on the lithography and laser cutting.

In some cases, laser features additional components to make this device more practical. They include beam shape, wavelength and polarization.
Facts about Lasers 4: the theoretical foundations
The theoretical foundations of laser were developed by Albert Einstein in 1917. The confirmation related to the stimulated emission and negative emission was made by Rudolf W. Landenburg in 1928.
Facts about Lasers 5: the short waves
The prediction related to the amplification of short waves by using the stimulated emission was made by Valentin A. Fabrikant in 1939.
Facts about Lasers 6: the optical pumping
The method of optical pumping was proposed by Alfred Kastler in 1950. He was a Nobel Prize winner in 1966.
Facts about Lasers 7: the improvement of laser
Laser has been improved for years. There is no need to wonder that the people develop it with different goals. Some people want to have a laser with minimum cost, new wavelength bands and maximum peak pulse power. Others want to have a laser with maximum power efficiency and maximum average output power.
Facts about Lasers 8: the modern communication
Laser plays a significant role for the development of modern communication. Internet is allowed to develop because of fiber optic laser.
