What to Look for in a Laser
The Six things that you want to look for in a laser are:
- Is it a true laser(s)?
- Does it have the optimal wavelength(s)?
- Does the laser have the ability to pulse and input frequencies?
- Can you vary the power?
- Is it easy to use and will it work for my office and my patient’s?
- How do I get the best bang for my buck when buying a laser?
What is a TRUE Laser?
The Avant Laser is a TRUE LASER, fully compliant to the definitions set forth by those great men of science such as Bose and Einstein who predicted LASER in 1924 and the contemporary physicists Schawlow and Townes who brought LASER into the modern age.
LASER is an acronym for Light Amplification by Stimulated Emission of Radiation. Light created in this way, is then culminated and directed into an intense beam of coherent light through the use of cathode and anode reflecting components in order to produce a single stable frequency. According to Webster's Dictionary, Lasers are coherent or marked by logical consistency.
The Avant Laser meets all the scientifically defined attributes of a laser and is therefore classified as a TRUE Laser. We assure and maintain this classification, through our unique and patented process, which produces the emission of coherent light, generated at a precise and stable frequency, and in a focused direction.
Light Emitting Diodes (LED) vs Laser = Bicycle vs Lamborghini
There are many light emitting products on the market today, claiming to be lasers that do not meet all scientifically defined attributes. For example, products that use Light Emitting Diodes or LEDs as they are more commonly known, do in fact produce light, however the light is not intense, producing very little energy and are non-coherent, similar to light produced by common household light bulbs.
Non-coherent or non-culminated light is the result of photons moving in random directions at random times, generating random frequencies. LEDs are cheap and easy to reproduce (Pontinen 1992, Lasers in Surgery and Medicine). Obviously, these devices are NOT lasers and this misconception is in large part a by-product of marketing.
There are thousands of Peer review research that supports optimal wavelengths for tissue repair and healing. In doing my research, I found that 630-640nm in Red and 808nm in Infra-Red wavelengths supported the greatest biological effects for laser therapy.
The 2 research articles from back in the 1990’s that really stuck with me were:
An article showed that when the DNA of a healthy cell replicates it admits light between 630-640nm. Laser therapy using the Red 637nm wavelength will create a bio-modulation effect to the cells that are out of balance. Thus, a cell that has a heightened state will decrease and normalize and a cell in a lower state will increase and normalize thus the bio-modulation effect.
The second article was by J.J. Andrews, United Arms Services, where she and her Team took rats and crushed CN VII to cause Bell’s Palsy in the rats. They then lasered the rats for 14 days in a row on the area of the crushed nerve. Not only did the peripheral nerve regenerate 35% faster than normal eliminating the Bell’s Palsy, but when they dissected that rats to check the brainstem for CNS cell loss, they found that almost 66% of the cells that normally died off where intact. This was a PROFOUND insight into laser therapy, that when you lasering a peripheral nerve it not only increases that nerve signal, but it also has stimulation to the Central Nervous System.
Low-Level Laser research articles conclude:
- DNA replication emits light between 630-640nm
- Cell Biomodulation
- Increases ATP production
- Increases phagocytosis
- Peripheral Nerve regeneration
- Promotes proliferation of fibroblasts and keratinocytes
- Increases skin circulation and microcirculation
- Increases enzyme activity
- Increases antioxidant activity
- Decreases Pain and Inflammation
- Pulsed lasers have a greater biological effect
Coherent Light, Frequencies and the Body
Laser frequencies or Hertz’s is when there is a pulsing that switches the laser light on and off repetitively. The frequency or speed of pulsing can be very slow and observable, or much faster than the eye can detect.
Devices that support pulsing typically cover the range of 1-10,000Hz (10,000 pulses per second). Clinical evidence has demonstrated that pulsing the laser light improves outcomes over a continuous illumination, and that the frequency of pulsing also effects treatment outcomes.
Coherent energy is critical when treating the body. Energy Medicine, The Scientific Basis gives several examples as to the importance of coherence.
The following are excerpts from this book: In the late 1960s, Herbert Frohlich, a Doctor of Physics, specializing in Biological Coherence predicted, on the basis of quantum physics, that the living matrix must produce coherent or laser-like oscillations. Dr. Frohlich's prediction was confirmed in a number of laboratories.
Of course, energy therapists of many schools have always recognized the importance of vibratory phenomena (including light) in healing, but academic molecular science was focused on other matters.
Dr. Frohlich's research goes on to report that coherent vibrations recognize no boundaries, at the surface of a molecule cell, or organism — they are collective or cooperative properties of the entire being. As such they are likely to serve as signals that integrate processes such as growth, injury repair, defense and the functioning of the organism as a whole.
Each molecule, cell, tissue and organ have an ideal resonance frequency that coordinates its activities. By manipulating and balancing the vibratory circuits, complementary therapists are able to directly influence the body's systemic defense and repair mechanisms.
I have repeatedly referenced Frohlich's hypothesis and the subsequent independent validation of findings that support, his prediction that crystalline molecular arrays should vibrate strongly and coherently. For an entertaining account of coherence and its biological significance, read The Rainbow and the Worm (Ho 1993).
Research on electrically polarized molecule arrays reveals that interactions repeated by the millions of molecules within a cell membrane, tendon, muscle, bone, nerve cell or other structure, give rise to huge coherent or laser like vibrations. James Oschman, author of Energy Medicine states "Crystalline components of the living matrix act as coherent molecular antennas, radiating and receiving signals.
Research on coherence in biological systems, is attracting much attention around the world. One important conclusion is that the water in the spaces between parts of the highly ordered systems is also highly organized. Vibrations of the water molecules can couple to the coherent energy patterns within the protein array.
The resulting coherent water system has laser —like properties, and is likely to retain and release electromagnetic information, i.e. have a form of memory (Del Guide et al 1988, Preparata 1995).
Frohlich (1978) An assembly of cells, as in a tissue or organ, will have certain collective frequencies that regulate important processes, such as cell division. Normally these control frequencies will be very stable. If, for some reason, a cell shifts its frequency, entraining signals from neighboring cells will tend to install the correct frequency. However, if a sufficient number of cells get out of step, the strength of the system's collective vibrations can decrease to the point where stability is lost. Loss of coherence can lead to disease or disorder.
While pathology may manifest as chemical imbalances, the underlying problem is electromagnetic. Hence providing the correct or healthy frequency, and entraining the oscillations back to coherence can often restore balance. These are profoundly significant concepts for all therapeutic approaches to the body. The whole field of chemical analysis by spectroscopy shows that there is a fundamental duality between chemical structure and coherent oscillations. Coherent vibrations in living systems are as fundamental as chemical bonds (Smith 1994).
Power: Laser Class 3 and Class 4
Laser power is without out a doubt the most controversial and confusing arena in laser therapy.
The laser class is purely a risk rating and does not equate to therapeutic performance. The higher the Class, the higher the Power and the higher chance for injury and burning due to increased heat production.
A Class 3 laser ranges from 1mW to 500mW.
A Class 4 laser is anything above 500mW.
Class 4 therapeutic lasers will often state that more power is better because higher, but lasers work best by their ability to stimulate the proper biological effects!
Therefore, I feel that it is essential to be able to control the power output of the laser to give you a larger treatment spectrum.
When we did the 1st FDA clearance clinical trials for chronic neck and shoulder pain, we used a low power 5mw, 635nm laser and we proved that when lasering the neck and shoulder for 10 minutes, the patient had a Decrease in Pain, Increased ROM and Increase Myotome Muscle strength.
A treatment dose using laser is the total energy delivered to the tissue and is calculated as the product of average power and time. Dose is measured in Joules (J). Sometimes dose is specified with respect to the surface area treated (usually in cm2) and this version of dose in J/cm2 is often referred to as fluence.
Although, J/cm2 is a very important way to calculate the amount of laser to be used for a certain area, it is equally as important to look a clinical changes throughout the laser treatment.
