Excimer laser was proposed in 1960 by Fritz Houtermans. [1] The excimer laser development started with the observation of a nascent spectral line narrowing at 176 nm reported in 1971 [2] by Nikolai Basov, V. A. Danilychev and Yu. M. Popov, at the Lebedev Physical Institute in Moscow, using liquid xenon dimer (Xe 2) excited by an electron beam.
The LiGHT trial compared the effectiveness of eye drops and selective laser trabeculoplasty for open angle glaucoma. Both contributed to a similar quality of life but most people undergoing laser treatment were able to stop using eye drops. Laser trabeculoplasty was also shown to be more cost-effective. [116]
Laser surgery is a type of surgery that cuts tissue using a laser in contrast to using a scalpel. [ 1 ] Soft-tissue laser surgery is used in a variety of applications in humans ( general surgery , neurosurgery , ENT , dentistry , orthodontics , [ 2 ] and oral and maxillofacial surgery ) as well as veterinary [ 3 ] surgical fields.
A year after federal investigators outlined how Chicago funnels industrial polluters into Black and Latino neighborhoods, Mayor Brandon Johnson vowed Monday to overhaul zoning, planning and land ...
The argon fluoride laser (ArF laser) is a particular type of excimer laser, [1] which is sometimes (more correctly) called an exciplex laser. With its 193-nanometer wavelength, it is a deep ultraviolet laser, which is commonly used in the production of semiconductor integrated circuits , eye surgery, micromachining, and scientific research.
A krypton fluoride laser (KrF laser) is a particular type of excimer laser, [1] which is sometimes (more correctly) called an exciplex laser. With its 248 nanometer wavelength, it is a deep ultraviolet laser which is commonly used in the production of semiconductor integrated circuits , industrial micromachining, and scientific research.

Lumonics was a global laser manufacturing company based in the Kanata North Business Park region of Ottawa.. Founded in 1970, [1] it was the first venture capital (VC) financed high tech company of the ones that based themselves there, [2] thus clearing the path (started by Computing Devices from nearby Bells Corners back in 1948) for the subsequent VC and start-up fueled growth that led to ...
