The blue laser

The blue laser has a distinct absorption for porphyrins on account of ist wavelength of 400-470 nm, consequently for hemoglobin too. So far there are only a few scientific data on clinical application with patients since it suceeded just a short time ago to build a solid blue semiconductor laser from galliumnitride. It became public that caries, paradontitis and acne can be treated with blue LED (light-emitting diode) with good success because they are also emitting monochromatic light (but without deepacting coherence). According to late researches Helicobacter pylori can be eradicated successfully by application of blue light over the gastroscope. The bactericide effects of the blue monochromatic light is binding to bacterial porphyrins and destroying them. Tiina Karu showed in several works that in the mitochondrial respiratory chain the red as well as the infrared laser light stimulates the last link of the respiratory chain (the so called cytochrome-C-oxidase), while the first link (the so called NADH dehydrogenase) has its absorption maximum in the blue range. So there is that possibility to stimulate this "starter complex" carefully by radiating with blue laser. This effect will be of considerable importance for the intravenous laser blood irradiation. From the works of the Armenian laser scientist Levon Gasparyan the first data are available already. He was able to show that under irradiation of the blood with blue laser light of low power (0,3 mW) the rheology of the blood will be significantly improved and as a result the microcirculation will improve, too. According to the latest data collected by him, also cases of tinnitus resistant to treatment can be treated more successfully than before.

Furthermore it was reported that metabolism effects lead to a significant decrease of cholesterol, triglycerides and blood-glucose and bilirubin. The immunologic activity of the blood is increasing significantly according to Gasparyan. Due to its proximity to the ultraviolet spectrum it is assumed that in the therapy of the blood the blue laser is also inducing the well-known immuno-stimulating effects as they are known from the UVB-treatment of the Blood.

In a work from October 2006, the blue laser was also used diagnostically to trace tumor cells. Due to strong absorption impulses of the blue laser cause melanoma-cells circulating in the blood to swing and to emit signals that can be recorded with highly sensitive microphones. This is called photoacoustic detection.
