We already heard about light and prism and the different colors of the rainbow. Let´s focus today on a special kind of light source: on laser light.
L-a-s-e-r stands for Light Amplification by Stimulated Emission of Radiation. Unlike sunlight that can be sent through a prism and will show all spectral colors that we know as a rainbow, laser light has only one wavelength showing only one color.
Nowadays we use laser light to scan our products at the cash of our grocery shops, for laser shows for entertainment, for laser printers, the police uses it for speed control, we can cut and cauterize etc.. Laser light is monochromatic – that means that is one-colored. Laser light is collinear- that means that the beam is bundled. Laser light is coherent- that means all light waves move in a photon stream which is in phase.
For health reasons it is interesting to work with one wavelength only – which laser light can provide us with- because we learnt that specific wavelength are absorbed by specific enzyme complexes located in our mitochondria. Mitochondria are the power plants of our cells that produce ATP which is the fuel we run on.
To be continued….
