-- Excimer laser light is typically absorbed within under a millionth of a meter (nanometer) of tissue. * * *a millionth of a meter is a micrometer, a billionth of a meter is a nanometer. Which one is it?* * *-->In 1980–1983, Rangaswamy Srinivasan, Samuel Blum and James Wynne at IBM’s T. J. Watson Research Center observed the effect of the ultraviolet excimer laser on biological materials.
It also operates five specialized medical service centers, namely: Cardiac Center, Glaucoma Imaging & Diagnostic Center, Excimer Laser Center, Chulalongkorn Craniofacial Center, and the Queen Sirikit Center for Breast Cancer.

Lower-energy femtosecond lasers may improve upon the traditional excimer laser by reducing disruption of ocular structures, with intrastromal ablation obviating the need for the damaging epithelial incision and ablation currently employed in LASIK and PRK procedures.
The Nike laser at the United States Naval Research Laboratory in Washington, DC is a 56 beam, 4-5 kJ per pulse electron beam pumped krypton fluoride excimer laser which operates in the ultraviolet at 248 nm with pulsewidths of a few nanoseconds.
