A Comparative Study of the Effects of Continuous Lasers and Pulsed Lasers on Human Red Blood Cells

Abstract

The notion of lasers has intrigued scientists and science-familiarized individuals alike for over three decades. Laser technology is currently used in various industrial, medical, military, and entertainment applications. High-tech research has documented speculations regarding the influence of low-energy lasers on biological tissues, especially human red blood cells. Research on the biological ramifications of laser radiation began as part of the Soviet Union's Cold War endeavor focusing on the effects of lasers on crops and personnel. Scientific investigations followed in the 1980s and afterward. M.R.S.A. commenced investigations in the field and secured recognition as a pioneer in local work. Illumination of lettuce with continuous-wave lasers is presumed to stimulate nitrogen metabolism and enhance biomass yield by around 10%. Previous investigations found that a 660 nm continuous-wave laser LED light source and a 632.8 nm HeNe laser adversely affected RBCs, with an increase in RBC size and a reduced degree of hemolysis.
