Green laser light frequency
In 1917, Albert Einstein established the theoretical foundations for the laser and the maser in the paper "Zur Quantentheorie der Strahlung" ("On the Quantum Theory of Radiation") via a re-derivation of Max Planck's law of radiation, conceptually based upon probability coefficients (Einstein coefficients) for the absorption, spontaneous emission, and stimulated emission of electromagnetic radiation. In 1928, Rudolf W. Ladenburg confirmed the existence of the phenom… WebMay 7, 2024 · LED green light therapy is a painless, relaxing procedure that has many benefits. With a wavelength of 510-560 nm, green light is absorbed by the skin ( up to 2 mm) and has a soothing effect. Helps to lighten hyperpigmentation spots for a brighter complexion. The soothing effect also has anti-inflammatory properties.
