  10. What low level laser(s) meet all these requirements?
  1. What does LASER stand for?
    LASER stands for Light Amplification by Stimulated Emission of Radiation.
  2. How does laser light differ from “normal” light?
    Light emitted from a laser diode is monochromatic (having only one wavelength), parrallel and coherent (having waves with similar direction, amplitude, and phase). These qualities make laser light much more valuable for therapeutic benefits.
  3. Are low level lasers SAFE?
    Cold laser practitioners conclude a resounding YES. Industry has been using low level laser diodes for years in such applications as bar code check outs, CD players, laser printers and pointers. The FDA has listed cold lasers or bio-stimulation lasers as non-significant risk (NSR) devices. Many of the low level lasers shown on this website have received UL approval for safety and FDA approval for sale in the US or FDA clearance for treatment of specific applications such as pain management.

  4. How do low level lasers or soft tissue lasers work?
    Pain results from trauma, inflammation and/or cellular disruption, malfunction, or less than optimal cellular function. Healing and pain relief come with cellular normalization or repolarization. Photons enable cells to perform optimally by stimulating them to initiate bio-chemical reactions, which produce enzymes and ATP (usable energy). Use of low level lasers (cold lasers or soft tissue lasers) enhances cellular function and it can also encourage the formation of collagen and cartillage in damaged joints and the repair of tendons and ligaments. Cold lasers and soft tissue lasers are gentle and non-heating to the tissues. They are configured with frequencies and power densities that are favourable to the cells and tissues of the body.
  5. Where can low level laser therapy be used?
    Low level laser therapy may be used any place there is acute or chronic pain or inflammation, and low level laser therapy may be effective on any dis-ease or disorder. Users have reported successes when using low level laser therapy on: Arthritis, Carpal Tunnel Syndrome (CTS), Tennis Elbow, Whiplash, Headaches, Back, Neck and Shoulder Pain, TMD/TMJ, Burns, Cuts, Sprains, Colds and Cold Sores, Sinusitis, and even Age Spots and Wrinkles!
  6. Have low level lasers been scientifically studied and proven?
    Low level lasers have been used world-wide for over 30 years.
    Over 2500 studies have shown that low level lasers are effective in the treatment of numerous conditions including:
    (1) REDUCE PAIN by stimulating cells to produce their own endorphins, natural pain killers and by relaxing muscles,
    (2) PROMOTE FASTER HEALING by stimulating cells to increase the production of two major healing enzymes by as much as 75%,
    (3) REDUCE INFLAMMATION by as much as 75% by deactivating 7 or the 9 enzymes responsible for causing inflammation.
    (4) INCREASE BONE REPAIR SPEED by stimulating fibroblastic and osteoblastic proliferation,
    (5) RELAX MUSCLES and muscle spasms,
    (6) DECREASE SWELLING by stimulating lymphatic drainage,
    (7) ENHANCE THE IMMUNE SYSTEM by increasing the number of “killer” cells by 400-900%, and most importantly,
    (8) RE-ENERGIZE or RE-POLARIZE CELL MEMBRANES to allow transport of essential nutrients across cell walls (nutrients will not cross an injured or sick cell wall, thus slowing healing) allowing the cells to speed up metabolic processes, convert newly received photonic energy from cold laser treatment to ATP and rebuild and regenerate at excellerated speeds.
  7. How much do low level lasers cost?
    We have seen low level lasers advertised for anywhere from $200 up to $20,000 each. Not all lasers are created equal. Cheap lasers usually incorporate only LED diodes, rather than true laser diodes. High quality laser diodes combined with LED diodes create a desirable laser healing tool. Cost is often a variable determined by the number of diodes a laser offers, plus the wavelength, power output and other factors such as continuous wave (CW), Pulsed Wave and Superpulsed wave.
  8. Does a higher price always mean a better low level laser?
    Not always. A VERY LOW price usually means that the product contains only cheap LED’s, and no true laser DIODES and while “LED only” products may provide some benefit, extensive research has concluded that they are not nearly as good as a product with both LED’s and a true laser diode. It is also not necessary to pay VERY HIGH PRICES (over $4,000) for an individual low level laser unit. Call our laser experts to explore your options. Phone toll free 1-888-824-7558.
  9. What features should I look for in a quality low level laser?
    1. A unit with both true Laser and LED diodes. Red light wavelength for treatment of skin and wound care and surface injuries and Infrared wavelength for acute or chronic pain and muscular skeletal and joint related conditions in which deeper penetration would be desirable.
    2. Lasers that are designed to both Harmonize and Resonate with the body’s natural energy. Sometimes referred to as multi frequency lasers because they are programmed to cycle through ideal Hz frequencies.
    3. The unit should be able to consistently control power output (more is not better) via a Computer-Controlled Power System.
    4. The laser should be able to produce Multiple Energy Levels and Multiple Wave Lengths. Not all conditions can be treated with a single wavelength.
    5. The laser diode(s) should be Polarized so as to energize the greatest number of cells.
    6. The laser energy should be Pulsed or superpulsed to encompass all frequencies in the brain.
    7. Programmability – the unit should be programmable as successful new frequencies are discovered.
    8. The unit should be convenient to use.
    9. Finally, the unit should be Reasonably Priced – meaning a suggested retail price between $2000 and $4000 (depending on features). In some cases it is worth spending considerably more for a laser that offers numerous attachments and a wide range of single and cluster probes and perhaps a scanner for the widest range of treatment options.
  10. What low level laser(s) meet all these requirements?
    The TerraQuant MQ2000 Laser v.5 meets all these requirements. So does the L.I.T.E. 4 Cold Laser Package and possibly others. For more information on a Cold Laser to meet your needs and budget or to place an order please call Toll Free 1-888-824-7558 or E-mail: send us a note
