Practical uses for the new source of light, which scientists christened laser (for light amplification by stimulated emission of radiation), proved to be both scarce and elusive.

The idea of a laser has outgrown its name. It is no longer exclusively “light amplification by stimulated emission of radiation.” Of course, many such examples exist in the English language.

Albert Einstein's stimulated emission theory has been validated by large amounts of light, but never before by individual photons—until now.

Understanding Laser Dentistry The term 'laser' stands for light amplification by stimulated emission of radiation. It is a sophisticated tool that emits a narrow, focused beam of light energy, which, ...

By 1953 the researchers had turned their theory into a working device, which they called a maser – an acronym for microwave amplification by stimulated emission of radiation.

Let’s start with the basics. The word laser stands for Light Amplification by Stimulated Emission of Radiation. A laser is made of light all with roughly the same frequency (or, in other words ...

Laser (light amplification by stimulated emission of radiation) was developed just six years later. During this time materials and technologies were found that would attain laser-wave parameters ...

New results published in the journal Physical Review Letters detail how a specially designed metamaterial was able to tip the ...

Scientists at Northumbria University have made a breakthrough in developing a new type of ‘microwave amplification by stimulated emission of ...
