What is Low Level Laser Therapy (LLLT)?

LASER is an acronym for Light Amplification by Stimulated Emission of Radiation. Low Level Laser Therapy or Cold Laser therapy is the application of specific wavelengths of coherent laser light, however some unique lasers such as the Scalar Wave Laser and Erchonia laser also deliver specific frequencies for added benefit and increased results. Frequency is measured in Hertz (Hz), a lasers' wavelength is measured in nanometers (nm) and a lasers' power is measured in Milliwatts (mW). Select laser light wavelengths supply the tissues at a cellular level with photons and electrons. Many Low Level Lasers exist under the following names: cold laser, soft laser, stimulating laser, resonating laser, quantum laser and so fourth. All of these Low Level Lasers are non-cutting, non-heat producing, gentle, therapeutic lasers.

Wavelength is the length of the light wave and is measured in millimeters (mm) most often expressed in nanometers (nm), which is 1/1000 of a millimeter. In the visible spectrum wavelength and color are basically the same. Laser light in the wavelength range of 600 - 700 nanometers (nm) results in visible red light, which penetrates up to 1/2". In the wavelength range of 701 - 1000 nm, invisible infrared Laser Light results, with a penetration depth up to 3". These two specific wavelength groups of coherent laser light are the most commonly used. They quickly help to activate the bodies innate cellular communication system and positive immune, enzyme and endorphin response. The most preferable red light wavelengths are 630-670 nm, and for infrared 780-905 nm.

Power density is the power output of a laser or laser diode and is measured in milliwatts (mW) or 1/1000 of a watt. Maintaining a constant power density is critical in Low Level Laser Therapy and is best achieved with a microprocessor or mini-computer.

Penetration is the depth a laser beam will penetrate into the body, dependant on the type of laser being used and the frequency range it applies (See above). Deeper penetraion means greater delivery of photons to target tissue if the target tissue is deep enough or hard enough to require it.
