With each MEDRAY treatment, the power and energy from the laser help to increase biologic circulation.
This causes an increase by absorbing more H20, 02, and specified nutrients to areas of damage and inflammation.
By doing this, a therapeutic heating zone is established that in turn helps to reduce painful inflammation, spasm of contributing muscles, swelling and associated areas of pain.
Because of the MEDRAY laser emission; these mentioned modalities help injured tissues and areas to return to a more homeostatic normalization.
MEDRAY Class IV therapeutic laser, with four distinct wavelengths, interacts at the cellular level.
This interaction increases the metabolic actions inside of the cell as well as affecting the cell membrane which thus allows for the increased flow of nutrients.
Because of this increased transport, ATP is excited with interaction through the cytochrome oxidate system.
This continued procession of expanded reactions thus continues the process of healing and pain reduction.
It has been well-established that different therapeutic wavelengths affect different tissues and at different levels.
It has also been well known that many Class Illb lasers, no matter the argument, do not have the power to reach deeper tissues.
If according to Class IIIb laser manufacturer’s wavelength was the only factor and not power, then there would be no use having a laser with any energy at all.
MEDRAY offers power levels and various wavelengths with the ability to reach both deep and superficial levels.
The four wavelengths, 650, 810, 915, and 980 address body compositions of soft tissue, bone, fat, and several fluids.
Pulsing or continuous wave both offer the optimal opportunities at influencing cellular healing and transformation.
MEDRAY offers a quad array of wavelengths, and as mentioned, all of these are specific for certain areas and levels of penetration:
Several laser manufacturers talk about super pulsing.
Some mention that their laser super pulses at a billionth of a second. One needs to realize how short a burst of energy this really is and how therapeutic that time frame can be.
Secondly, super pulsing can only be capable of what the laser diode can handle structurally.
If your laser is designed to be a 500mw (Class IIIb laser), how can the diode take a burst of energy that is 1000 times its normal operating power level.
Imagine a 60w light bulb given a jolt of electricity 100 times its median value.
Even a millisecond of energy would burst the bulb.
Laser diodes are manufactured to accept certain and maximal levels of power, not 1000 times what it was manufactured for.
Super pulsing may and could be a viable tool.
However, some claims appear to be beyond what the physical capability of the laser diode can handle based on their manufactured capability.
Several laser companies in order to market their lasers use Techno -Babble which is using technical sounding terms, which are not necessarily proven, to impress potential customers.
Super pulsing may give a high peak power, but the average output of super pulsed lasers is comparatively low.
Even though peak power of the super pulsed laser may be very high, it lasts for an extremely short time compared to the pulsed cycle, resulting in an average output power that is usually a thousand times lower than the peak power. For clinical use, it is the AVERAGE POWER that is beneficial.
Some manufacturers prefer to label these lasers as “very strong” and state only the peak power which then can be in the order of 100 watts. This sounds impressive, but typically these lasers emit 10 – 100 mW average power, and this is what counts for treatment.
One manufacturer promotes it’s super pulsed lasers as having 25,000 mW or 50,000 mW of power. It has just a few presets. To calculate the average power, one must only know the Peak Power, the Pulse Frequency and the Pulse Duration.
If the manufacturers “highest” power option of 50,000 mW is used, and consider the longest possible pulse duration is .0000002 sec for calculation purposes, the AVERAGE OUTPUT POWER is only .050 mW or fifty millionths of one Watt.
With is very low average power, it will take twenty thousand seconds or 5.6 hours for this manufacturer’s laser to deliver one Joule.
When speaking to a sales rep, many of them will not really know the so called scientific principles regarding Super Pulsing, and resort to more Techno Babble in order to sell a laser that actually delivers less.
It should be noted, that a world renowned-laser expert on Class IV laser and physics said the following:
“In physics there is no such thing as ‘super-pulsing.’ There is no way a nano-second pulse of light can influence organic tissue in vivo, other than to ‘blind’ it with high luminescence. Photo-chemical changes occur when an energy threshold transference (volume of energy) is achieved – nanosecond-pulse lasers produce minimal energy transference, far too low to produce a photo chemical change.”
If wavelength has been determined to generate the beams extent of infiltration, than the power predisposes the superabundance at the intended depth.
Having one without the other is a futile attempt to obtain a satisfactory result.
The power of the laser equates to a specific number of photons that can be delivered over an assemblage of time.
Placed energy is measured in Joules.
1 watt of power equates to 1 Joule of energy per second. Beginning with more watts of power at the surface level equates to more ingression to the relevant depth.
Simply stated, a 10w deliverance of Medray power would give 600 Joules of therapeutic energy to the desired cellular level in one minute.
A Class IIIb laser at 500mw, would take 20 minutes to deliver the same amount of healing energy, that MEDRAY does in one minute.
This equates to faster treatment and healing times.
Wavelength, skin penetration and laser power can be compared to simple mechanics that are true in several applications.
Imagine your skin as a board. The wavelength is a nail and the power emitted by the laser is a hammer. There is no way for the nail (wavelength) to penetrate the board (your skin) without the power of the hammer (laser power in watts).
No matter the size of nail (wavelength), or its potential to penetrate, it cannot do so without the hammer (laser power in watts). This is a basic law of physics and applied mechanics.
D=WL x P x T (Depth = Wavelength x Power x Time)
It should be noted that many Class IIIb laser manufacturers talk about the problems associated with Class IV laser. such as too much power.
Yet, they then preach about how their laser can “super pulse” into Class IV parameters and beyond.
They want to continually be compared to Class IV laser therapy because of it’s obvious benefits such as short treatment times and faster healing and pain relief but they then degrade Class IV laser for the same reasons they want to be compared with.
