From Twente University: "In the development of laser technology, excimer lasers operating in the ultra-violet may be considered as the third generation of industrial lasers. The short wavelength, or, in other words, the high photon energy of excimer lasers, leads to a wide range of new applications.

Excimer stands for excited dimer, a diatomic molecule usually of an inert gas atom and a halide atmon, which are bound in excited states only. These diatomic molecules have very short lifetimes and dissociate releasing the excittion energy through UV photons."

Adapted from ANL Press Release: " discovery by three Argonne scientists that high-intensity beams of light with a wavelength of 308-nanometers — the energy produced by excimer lasers — can remove abnormal tissue without harming surrounding healthy tissue. This finding led to the field of laser angioplasty and is now used worldwide to treat clogged and plaque-filled arteries, occluded vein grafts, and impacted or infected pacemaker and defibrillator leads.

“It was our recognition of the fact that the near-ultraviolet radiation of this laser can be transmitted with very little loss of energy through a quartz fiber-optic catheter that made possible the application of laser surgical procedures to cardiovascular disease " Dieter Gruen

Conventional lasers require such high energies to remove tissue — and generate so much heat in the process — that they often harm surrounding healthy tissue 

But excimer laser beams don't generate heat. Instead they turn tissue directly into gas by breaking chemical bonds. Argonne’s development stemmed from basic research on specialized techniques that use lasers to examine systems ranging from fusion energy plasmas to the composition of meteorites.

From Kremmer Eye Center: "An Excimer laser is a device, which generates a 193-nanometer wavelength beam of light. It is capable of removing extremely thin layers of corneal tissue without damaging adjacent areas."

Manufactureres: "GAM LASER INC. has manufactured a line of very long life, rugged, high reliability excimer lasers and 157nm Fluorine lasers for industrial, medical and scientific applications"
