Laser Terminology
As you research Laser Therapy, here are a few terms to help you understand.
Absorption- All wavelengths are absorbed by some media. Example CO2 lasers, which are in the far infrared spectrum, are absorbed by water and NdYag lasers emitting near infrared are absorbed by pigment. Absorption affects the overall benefits of low level lasers.
A canceling wave is a wave of the exact same form and frequency moved 1/2 cycle from the original wave, resulting in no wave. This is the principle used by Rife to neutrilize or "hold harmless" waves from diseased tissue or waves from invading bacteria, viruses, or parasites.
Coherence means that these photons are well ordered and travel parallel to one another in the lazy S motion or "sine wave" and are monochromatic meaning, they are of the same color. These two principals are the main differences between laser light and regular light.
Collimation means that the laser beam has been focused down to a smaller spot size. Collimating a laser beam increases the power density. Low level lasers discussed in this manual for pain control and healing are not collimated like laser pointers.
Electrodynamic fields- As light travels forward, it also oscillates up and down in a wiggling "lazy S" motion creating an electrodynamic field. These fields control all life.
Electromagnetic spectrum expresses all wavelengths known on earth and includes the very short cosmic rays, gamma rays, x-rays, ultraviolet rays, visible light waves, infrared waves, and microwaves up to the very long radio waves.
Energy- Everything on earth is energy. Energy cannot be created or destroyed, only transformed.
Frequency is the number pulses per second or the number of times a wave is interrupted (started and stopped) per second. Regardless of the length of a wave, the wave can oscillate at different frequencies and these frequencies are very specific. A basic fact of laser physics is that movement alters frequencies.
Joules is the amount of energy delivered by one watt of power in one second. The formula for calculating joules is output x time / area and is critical in determining if a laser is resonating or stimulating.
Infrared waves are longer than visible waves and are invisible to the human eye. All lasers used for pain control and healing are in either the visible or infrared wavelengths.
Laser- Light Amplification by Stimulated Emission of Radiation
LED means light emitting diode. The emitted light is not coherent therefore is not the same as laser light.
Low Level Laser- is a laser that produces less than 1 watt of energy. Other names are Soft Laser, Cold Laser, Light Therapy, Light Healing, and Photodynamic Therapy. Any wavelength laser can be made into a higher output laser that cuts by increasing the milliwatts (mW) of power. The resonating lasers discussed in this manual are reted at 5 mW or below and the stimulating lasers are above 5 mW up to 500 mW.
Photons are small packets of light in the form of a wave element with a defined wavelength and a frequency related to that wavelength. The packets of light energy are produced when atoms are excited and thus move the photon to the outer orbit of the atom producing transformed energy.
Power density is the output power of a laser and is measured in milliwatts (mW) or 1/1000 of a watt. The formula for calculating power density is Watts/cm2. Maintaining a constant power density is critical in low level laser therapy.
Penetration is the depth a laser beam will penetrate into the body and is the limiting factor of all low level lasers. Visible laser light ranging from 400 nm to 700 nm (blue, green, red) penetrates 1 to 3 mm. Infrared ranges from 700 nm to 1000 nm penetrates 4 to 10 cm.
Solition Wave is a non-linear light wave that maintains its shape and increases amplitude after colliding with a similar wave. This increased amplitude of combined wavelengths allows the soliton wave to penetrate deeper into the body by increasing the power density. While increasing the power dinsity may wark to stimulate certain parts fo the boky, increasing the power density actually reduces the resonating capability of low level lasers. The soliton wave is the greatest breakthrough in low level lasers and makes it possible for subtle energy to penetrate deep into body tissues and resonate cells.
Polarization is the body's way of protecting itself against unpredictable energy such as electromagnetic contamination. Polarization is also described as impedance or resistance and is triggered by higher power density low level lasers or lasers that do not have a computerized constant power density and constant frequency control. This is a limiting factor of many low level lasers thus compromising their success and preventing low level lasers from being more popular.
Visible light waves are waves seen by the human eye. The visible spectrum starts with white, light blue, blue, blue green, green, yellow, orange, and red. Black waves are not visible to the human eye.
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, wavelengths and color basically are the same.+
