Green laser therapy

In the beginning of 2005, Weber for the first time used a green laser for the intravascular blood treatment.

The basic idea was to increase the blood’s energy assimilation by the absorption of green laser light as a complementary colour to red light to the erythrocytes.

When switching-on a red light laser with an intravascular position of the catheter, a red spot will shine spontaneously through the skin, as the red haemoglobin of the erythrocytes reflects the red laser light.

When switching on a green laser with a wavelength of 536 nm, virtually no visible green spot appears on the skin, as the laser light of this wavelength is almost completely absorbed by the haemoglobin.

A group of 20 liver patients and 20 lipometabolism patients was treated with a mere green laser therapy. As a result, the green laser seemed to be slightly more effective than the red laser.

The red/green laser therapy that was applied subsequently (20 min. red and 20 min. green) obtained an additionally improved effect. Therefore, the author considers this therapeutical principle as the optimal method.

Comparison of red laser (632,8 nm) and green laser irradiation (532 nm) in the rheology of the blood

Blood cells were radiated in vitro with the wavelength 632,8 nm (helium-neon laser) and 532 nm (green laser). In these experiments it could be shown that the green laser had an advantage of rheologic properties of the blood by an improved forming property of erythrocytes. The corresponding absorption spectrum for haemoglobin was assumed as cause for the green laser in particular.
