Wavelengths Wavelengths are Measured in Nanometers
The biological effect of laser therapy is related to the wavelength of light emitted by the laser:
Different wavelengths target different tissues, e.g. blood, melanin, water, etc.
These Targets are Known as Chromophores
Wavelengths INFRA-RED 193 nm 400 to 700 visible 532 nm 1064 nm 755 nm 10.2 μ m
The treatment beam of the Pilot Laser System has a wavelength output of 820nm, proven to be optimal for surgical and therapeutic laser treatment.
Laser Light is Very Different From Normal Light
Laser light has the following properties:
MONOCHROMATIC The light emitted from a laser is monochromatic , on other words, one wavelength (color). In contrast, ordinary white light is a combination of many different wavelengths (colors). LASER PROPERTIES
Pulsed Emmissions The words pulsing and frequency are used interchangeably to describe the same concept, which is the interruption of energy flow on a predetermined basis. Some manufacturers have laid claim to special frequencies, claiming that they produce better clinical outcomes. Peak Power = pulse energy/pulse x duration A 75 W peak power system with a 1 ms pulse has a pulse energy of 75 mJ… Power = pulse energy x rep rate; 75 mJ laser at 10 Hz = 750 mW
Continuous Wave Emission Continuous wave emission lasers have no interruption during the delivery of their energy
Pilot DVM-T/S Class IV Medical Laser Surgical and Therapeutic Laser Surgical Laser: Used to cut, coagulate and evaporate tissues. This type of laser replaces the scalpel. Therapeutic Laser: Used for the stimulation of cell function. The biological effect is photochemical as well as thermal, unlike surgical lasers.
Laser-Tissue Interaction PHOTO-THERMAL long pulses, biological effect due to heating, hair removal, most surgical lasers PHOTO-MECHANICAL S hort-pulsed (q-switched) lasers cause ablation tattoo removal PHOTO-CHEMICAL laser causes chemical change or response-pain relief
Photo Chemical A photo-chemical treatment is where the light has a chemical impact on the tissue being treated. Examples include: Photo Dynamic Therapy (PDT) Cancer treatment, ophthalmic treatments Laser Therapy pain relief
Absorbtion Cellular action spectra has been determined to be from 500 nm to 1100 nm The Chromophore (photoreceptor) is believed to be Cytochrome C Oxidase, which is in the mitochondria and is instrumental in cellular respiration .
Important Factors For effective penetration, light needs to avoid scattering and surface absorption.
Scattering A beam of light focused on tissue may be reflected, absorbed, or scattered. Scattering is wavelength dependent. Longer wavelengths have less scattering. Scattering in tissue broadens the incident beam, decreasing the effective fluency in the intended target area. Doubling the spot size will increase the effective volume by a factor of eight.
The Importance of Power The main reason cited for negative findings in therapeutic laser studies have primarily been because of the use of very low dosages.
The Power of the Pilot DVM Laser Power = Energy/Time 1 Watt = 1 Joule/Second Your 9 watt Pilot DVM Therapy Laser™ delivers 9 joules/sec. Over a period of one minute your laser delivers 9 joules/sec x 60 sec/min = 5400 Joules/min .
Power Density vs. Energy Density Power Density (irradiance) The power of the laser per unit area Irradiance (PD) = W/cm2 Energy Density (fluence) The power density multiplied by the exposure time, measured in Joules/square centimeter Fluence (ED) = Joules/cm2
Power Comparison The Erchonia 3LT™ laser PL3000 5mW laser delivers 0.005 joules/sec. Over a period of one minute this device delivers 0.005 joules/sec x 60 sec/min. = 0.3 joules /min. The Respond 2400XL500P™ has a 500mW head delivering .5 joules/sec. Over a period of one minute this device delivers .5 joules/sec x 60 sec/min. = 30 joules/min. The Pilot DVM Therapy Laser™ delivers 540 joules/min
Spot Size & Power Density Spot Size The advanced solid state technology and the innovative hand-piece of the Pilot Therapy Laser™ safely delivers a high dose of photons over a large area Power Density Indicates the degree of concentration of the power output.

Acute Inflammation Reduction How does Photobiomodulation reduce inflammation? Stabilization of the Cellular Membrane • Ca++, Na+ and K+ concentrations, as well as the proton gradient over the mitochondria membrane are positively influenced. This is accomplished in part by the production of beneficial Reactive Oxygen Species aka (ROS). • These ROS’s modulate intracellular Ca++ concentrations and laser therapy improves Ca++ uptake in the mitochondria.
Acute Inflammation Reduction Stabilization of the cellular membrane Enhancement of ATP Production and Synthesis ATP production and synthesis are significantly enhanced, contributing to cellular repair, reproduction and functional ability Photonic stimulation of Cytochromec Oxidase, a chromophore found on the mitochondria of cells, plays a major role in this rapid increase in production and synthesis of ATP.
Stimulation of Vasodilation Vasodilation is stimulated via an increase in Histamine, Nitric Oxide (NO) and Serotonin levels, resulting in reduction of ischemia and improved perfusion Laser-mediated vasodilation enhances the transport of nutrients and oxygen to the damaged cells and facilitates repair and removal of cellular debris.
Acceleration of Leukocytic Activity Beneficial acceleration of leukocytic activity results in enhanced removal of non-viable cellular and tissue components, allowing for a more rapid repair and regeneration process.
Acute Inflammation Reduction Increased Prostaglandin Synthesis Prostaglandins have a vasodilating and anti-inflammatory action
Reduction in Interleukin 1 Laser irradiation has a reducing effect on this pro-inflammatory cytokine that has been implicated in the pathogenesis of rheumatoid arthritis and other inflammatory conditions.
Enhanced Lymphocyte Response In addition to increasing the number of lymphocytes, laser irradiation mediates the action of both lymphatic helper T-cells and suppressor T-cells in the inflammatory response. Along with laser modification of beta cell activity, the entire lymphatic response is beneficially affected by laser therapy.
Temperature Modulation Areas of inflammation typically demonstrate temperature variations with the inflamed portion having an elevated temperature. Laser therapy has been shown to accelerate temperature normalization, demonstrating its beneficial influence on the inflammatory process.
Decreased C-reactive Protein and Neopterin Levels Laser therapy has been shown to lower the serum levels of these inflammation markers, particularly in rheumatoid arthritis patients
Acute Inflammation Cascade Pilot DVM Therapy Laser Treatment Cytochrome Activation Cell Membrane Changes ATP Increase Increased Leukocyte Activity Angiogenesis Proton Gradient Change Enhanced Lymphocyte Response SOD Production Ros Production Ca, Na, K Ion Changes IL-1 Decrease Temperature Modulation Vasodilation PG Synthesis
Analgesia How Does Photobiomodulation with the Pilot DVM Therapy Laser™ Reduce Pain? Increase in beta endorphins The localized and systemic increase of this endogenous peptide after laser therapy irradiation has been clinically reported in multiple studies with subsequent pain reductions.
Increased Nitric Oxide Production Nitric oxide has both a direct and indirect impact on pain sensation. As a neurotransmitter it is essential for normal nerve cell action potential in impulse transmission activity and, indirectly, the vasodilationeffect of nitric oxide can enhance nerve cell perfusion and oxygenation.
Decreased Bradykinin Levels Since Bradykinins elicit pain by stimulating nociceptive afferents in the skin and viscera, mitigation of elevated levels through laser therapy can result in pain reduction .
Increased Nerve Cell Action Potentials Healthy nerve cells tend to operate at about -70 mV, and fire at about -20 mV. Compromised cell membranes have a lowered threshold as their resting potentials average around this -20 mV range. That means that normal non-noxious activities produce pain. Laser therapy can help restore the action potential closer to the normal -70 mV range.
Axonal sprouting and nerve cell regeneration Several studies have documented the ability of laser therapy to induce axonal sprouting and some nerve regeneration in damaged nerve tissues. Where pain sensation is being magnified due to nerve structure damage, cell regeneration and sprouting may assist in pain decrease.
One of the truly unique characteristics of THE PILOT DVM THERAPY LASER™ is that it has the ability to actually promote and enhance healing, not just treat symptoms.
The irradiation by therapeutic laser light accelerates and enhances healing activities carried out by the body.
THE PILOT DVM THERAPY LASER™ mediated reduction in inflammation and pain frees the body’s natural ability to repair and heal itself.
As wound healing progresses through the stages of inflammation, proliferation, remodeling and maturation, laser therapy presents the opportunity to impact each of these phases in positive and beneficial ways.
THE PILOT DVM THERAPY LASER™ can provide the following beneficial impacts in both open surface wounds and closed connective or soft tissue injuries as follows:
Mechanisms Behind Tissue Healing Enhanced Leukocyte Infiltration The PILOT DVM THERAPY LASER™ stimulates activity involving neutrophils, monocytes and lymphocytes.
Mechanisms Behind Tissue Healing Enhanced leukocyte infiltration The PILOT DVM THERAPY LASER™ accelerates macrophage activity in phagocytosis, growth factor secretion and stimulation of collagen synthesis .
Keratinocyte Proliferation The beneficial synthesis activities and growth factor ability of keratinocytes are enhanced by proliferation secondary to the PILOT DVM THERAPY LASER™ . Mechanisms Behind Tissue Healing
Growth Factor Increases Two to five fold increases in growth-phase-specific DNA synthesis in normal fibroblasts, muscle cells, osteoblasts and mucosal epithelial cells irradiated with infrared light are reported.
Enhanced Cell Proliferation and Differentiation Laser induced increases in nitric oxide, ATP, and other compounds that stimulate higher activity in cell proliferation and differentiation into mature cells.
Greater Healed Wound Tensile Strength In both soft tissue and connective tissue injuries, the PILOT DVM THERAPY LASER™ can increase the final tensile strength of the healed tissue. By increasing the amount of collagen production/synthesis and by increasing the intra and inter-molecular hydrogen bonding in the collagen molecules, laser therapy contributes to improved tensile strength.
When not using laser, keep in standby or OFF mode.
NEVER look into the laser probe or into the direct path of the laser beam.
