GLASS LASER Meaning and
Definition
-
A glass laser is a type of laser that utilizes a solid-state material made of glass as the active medium. It works based on the principle of stimulated emission, wherein photons are emitted from excited atoms or ions, producing a coherent and focused beam of intense light. The glass used in this type of laser is doped with various rare-earth ions or transition metal ions, providing the necessary energy levels for lasing action.
The glass laser typically consists of a laser cavity, which includes a pair of mirrors that reflect the light back and forth, creating an optical feedback loop. The glass medium is excited by an external source like flash lamps or diode lasers, stimulating the emission of photons in a narrow wavelength range. Due to the properties of the glass material, the laser emission can occur in a wide range of wavelengths, including visible, near-infrared, or infrared regions.
Glass lasers find applications in various fields, including telecommunications, medical procedures, scientific research, and military. They are often used in fiber optic communications to amplify signals or convert them between different wavelengths. In medicine, they can be employed for various purposes such as tattoo removal, eye surgeries, and skin treatments. Glass lasers also serve as powerful tools for studying materials, conducting spectroscopy experiments, and in industrial applications like cutting and welding.
In summary, a glass laser is a laser that utilizes a glass medium containing doped ions, resulting in the emission of coherent and intense light. It finds extensive use in telecommunications, medicine, research, and industrial applications.

Etymology of GLASS LASER
The term "glass laser" does not have a specific etymology, as it is a combination of two separate words: "glass" referring to the material used in the laser resonator, and "laser" which is an acronym for "Light Amplification by Stimulated Emission of Radiation".
The word "glass" originates from the Old English "glæs" and is derived from the Proto-Germanic "glasam". It is likely related to the Latin word "glacies", meaning ice, as glass is a transparent material that can resemble ice.
The term "laser" was coined in the 1960s when the first functioning laser devices were developed. It was derived from the acronym "LASER", which stands for "Light Amplification by Stimulated Emission of Radiation". The term was coined by American physicist Gordon Gould, who is credited with its invention.
