argon laser The argon laser is filled with argon gas that produces blue/green wavelengths. These particular wavelengths are absorbed by the cells that lie under the retina and by the red hemoglobin in blood, but the blue-green wavelengths can pass through the fluid inside the eye without damage. For this reason, the argon laser is used extensively in the treatment of diabetic retinopathy, a severe disorder of the retina that causes blood vessels to leak. ...

argon Argon, #18 on the periodic table, is colorless and odorless, like all of the noble gases. It has an atomic mass of 39.948 amu, and its electron levels are 2-8-8. Ar was discovered by Lord Rayleigh and Sir W. Ramsay in England. It melts at 83.95 K, and boils at 87.45 K. Many people don't realize that argon makes up a full 1% of our atmosphere, while carbon dioxide is only a fraction of a percent of our atmosphere. ...
