    • Ayurvedic Physician Charaka-healing using sunlight (3)
  • 400 BC
    • Aristotle proposed that “light travels in waves” (3)
  • 300 BC
    • Euclid of Alexandria-theory of Light
  • 965 AD
    • Alhazen-scientific work-optics and provided the basis for European Optical Research (3)
  • 1253
    • Robert Grosseteste, Bishop of Oxford; wrote Cosmogenoy of Light: all matter is light (3)
  • 1619
    • Descartes-theory was that light was motion later called “the wave theory of light” (3)
  • 1672
    • Sir Isaac Newton discovered the visible light spectrum by separating light through a prism. (1)
  • 1858
    • Max Plank-first to suggest that light=photons=energy. Started Quantum Theory (3)
  • 1860
    • Michael Faraday-modern ‘Field’ Theory (3)
  • 1876
    • Augustus Pleasanton; blue light- relaxes glands, nervous system, organs (3)
  • 1878
    • Edwin Babbitt; developed chromadisc for delivering light to the body (3)
  • 1887
    • Seth Pancoast; red light to stimulate and blue light to relax the autonomic nervous system (3)
  • 1890
    • Nils Finsen began work on UV light (3)
  • 1903
    • Niels Finsen of Denmark was awarded the Nobel Prize by using ultraviolet light to successfully treat tuberculosis, rickets, and lupus vulgaris. (1) He believed at the time that this success was attributed to ultraviolet light killing the bacteria, but scientists have since shown that the system he used did not allow such short wavelengths to pass through. Therefore it has been concluded that light of approximately 400 nm generated reactive oxygen that would kill the bacteria. (2)
    • Finsen also used red light to treat smallpox lesions (2) skin ulcers (1)
  • 1916
    • Albert Einstein theorized that “when a photon of the correct energy level collides with an atom that has been energized under the right conditions, two photons of precisely the same energy would be emitted.” (1) He coined this term, “stimulated emission” in his theory Zur Quantum Theories der Strahlung(2) (FIND OTHER SOURCE-don’t like this one… very biased, says untrue things)
  • 1920s
    • Roayl RIFE; polarized light and frequencies for bacteria, virus (3)
    • Dinshah Ghadiali; developed spectrachrome and tonation system for delivering light to the body, women’s issues (3)
    • Harry Spitler; developed 19 Syntonic Principles or effects of light on body and mind. His system delivered light through the eyes (3) treat visual dysfunctions, head trauma, headaches, and problems with learning and behavior
  • 1923
    • Russian Alexander of Russia “observed that infrared light could be transmitted from a test tube to another adjacent test tube without any physical contact between the two of them. He used the term mitogenic radiation to describe this process.” (1)
  • 1930
    • Auguste Rollier; TB, Ulcers with sunlight (3)
  • 1940
    • Emmitt Knott; UV blood irradiation
  • 1947
    • Arvanitaki and Chalazonitis reported how light directly excited or inhibits nerve firings, depending on the wavelengths of light (RLT??)

    • Paul Nogier, MD; his frequencies based on the base Note of D and subsequent harmonics (3)
  • 1960
    • “May 16, Theodore Maiman produced the first Ruby laser at the Hughes Aircraft research laboratory in Malibu, California.” (1)
    • “November, Peter Sorokin and Mirek Stephenson at IBM laboratories produced the first uranium laser.” (1)
    • Russian Space Agency; cosmonauts, sleep, bones, muscles (3)
  • 1961
    • The first helium–neon (HeNe) laser is invented (4)
  • 1962
    • Goldman-first SURGICAL medical application (5)
  • 1963
    • In cardiovascular SURGERY McGuff first used a Ruby-Laser in 1963 for the experimental ablation of atherosclerotic plaques (5)
  • 1967
    • Endre Mester from the Budapest University in Hungary is credited as being the “father of laser therapy” for his discovery of photo-bio-stimulation. This discovery came to light when Mester did an experiment to determine if laser irradiation caused cancer. To determine this, he shaved the backs of two groups of mice. The first group was exposed to the energy of a low-power laser while the second was not, acting as the control. Not only did the first group that was exposed to laser irradiation NOT get cancer, but their hair grew back more quickly than the unexposed group. (1) (4 [72]) His findings were published in a Hungarian medical journal, not in an international distribution. This led to the benefits of laser therapy being utilized in this part of the world prior to the West. (1)
    • Mester also used a helium-neon (HeNe) laser to stimulate wound healing in mice (70). Mester also used lasers to treat non-healing skin ulcers on humans (4 [69, 71]).

    • Yo Cheng Zhou holds the first record of stimulating acupuncture points with a laser. Zhou was an oral surgeon in China who began using laser treatments as a local anesthetic for routine dental extractions. “His protocol involved therapy of 2-6mW of a red beam laser to a single point for 5 minutes. The tooth was them removed. Laser therapy was then applied to Hegu, the distal acupuncture point with recognized anesthetic properties.” (1)
  • 1970s/1980s
    • “Laser therapy spreads to Western European countries. These early reports using these modalities to perform physical therapy involved lasers that were only in the 5-10 mW range. Soon thereafter, the laser therapy appeared in the United States. In 1981, available lasers were in the 1 mW range and were manufactured in China.” (1)
  • 1980s
    • Semmelweis University, Budapest; mice, cancer, cells (3)
