Abstract
Abstract
The optical effects of laser irradiation on whole human blood were studied. The normal blood samples were taken from healthy persons and the blood samples were exposed to laser beam. Three wavelengths of continuous wave (CW) for diode pumped solid state
lasers (DPSSL S) were used to irradiate the blood samples. The wavelengths are (632 nm, 532 nm,473nm and405 nm ) and output varied between ( 3.9, 50,20 and 4.5) mW respectively. The laser exposure time fixed between (5 and 10 ) min for each wavelength. Laser radiation has a great role in the absorption properties of the normal human blood after being compered with absorption spectrum of a non-irradiated sample.
