Laser Gas Mixture Suppliers Pittsburgh

Let's discuss how lasers work because this is some cool science! Gas lasers are made by passing an electric current through one of several certain noble gases or gas mixtures. The electricity excites the electrons within the gas's atoms and elevates them to highly energized orbits around their atoms' nucleus. When the electrons return to their normal, lower energy state, the electrons will emit particles of light called photons. 

What's neat about photons is that the light they emit is a consistent wavelength dependent on the amount of energy that was released. Since all the energy is of the same wavelength, only one color in the color spectrum will be emitted. Emitting variations in wavelength produces natural light, but a uniform wavelength will create a single color, such as red or blue. The other distinct factor about laser light is, it is directional, making a beam of consistent light that doesn't diffuse; lasers can keep a focused beam for miles, a characteristic termed as "coherent."  

It's easy to remember how laser beams work when you think about the acronym -- "Light Amplification by Stimulated Emission of Radiation." Here at Greco Gas, we talk about gas lasers, but lasers can also be made by passing the electricity through glass or crystals. They are instrumental in consumer electronics like CD and DVD players, measuring, munitions, computing and surgery.
