HARLAS 650nm+810nm+980nm+1064nm laser system - Act the most effection for therapy 

LASER therapy has become progressively popular in the management of a wide variety of medical conditions. Laser is absorbed in the tissue, in turn, stimulates metabolic processes and improves wound healing.

Although Low level laser therapy (LLLT) has been widely used as the object of removing the inflammation or the pain, LLLT was too weak to reach deep tissues for making their effective treatments. Many authors have reported the benefits of LLLT on tissue healing, but others have shown no effect in their clinical studies. To overcome the insufficient light energy to the interested regions, High intensity light therapy (HILT) for pain has introduced. HILT delivers high amounts of photons directly to the injured tissue which accelerates the cellular reproduction. HILT involves high-intensity laser radiation and which causes minor and slow light absorption by chromophores.

For laser therapy applications, it is important to know the penetration depth and the overall distribution of laser light in deep tissue depending on the laser wavelength to determine the volume of the tissue where the laser-induced photobiological reactions when applying laser treatments.

The diffusion reflectance to light transport in tissue provides an excellent estimation of penetration depth for applications in which tissue scattering is the dominant optical interaction with light. In human tissue, the propagation of light within tissue is known to be complex. Although detected region is same tissue type, the mean and effective penetration depths varies according to the thickness of each tissue layer (skin, fat, and muscle), tissue type and applied laser wavelength.

In the skin tissue, the highest diffuse reflectance and laser fluence were achieved at λ=1064 nm, followed by, in order, λ=650 nm, λ=810 nm and λ=980 nm. Light absorption is influenced by both the wavelength and the composition of the tissue. Because melanin and water have a wavelength-dependent absorption coefficient, the distribution of these components (melanin, water) influence the optical properties of skin. The light absorption by water in tissue is higher at λ=1064nm than visible wavelengths. Thereby, the high diffuse reflectance, which was also found at λ=1064 nm with short radius, may arise from high absorption by water in the skin tissue. λ=650 nm wavelength has high absorption of chromophores such as melanin determines a small penetration depth of light into the skin tissue and correspondingly, larger diffuse reflectance than other wavelength. On the other hand, Chromophores contained in the epidermis absorbs less in the near IR range (λ= 810 nm, 980 nm, and 1064 nm) than in the visible range (λ= 650 nm) of the spectrum, the μ a at λ=810 and λ=980 nm in skin is lower than other wavelength. On the basis, it appears that λ= 810 and λ=980 nm decrease absorption in skin and small diffuse reflectance.

Dimed Laser uses the newest technolohy to combine the 650nm, 810nm, 980nm, 1064nm in one laser system, the 4 wavelength can make compensation for the penetration and absorption in water, melamin and hemoglobin. This laser will act the most effection for therapy.
