…blood vessels in the
retina. The laser then acts to seal the leaking vessels that are obscuring the retina. Coherent
diode lasers with longer wavelengths beyond the normal retina response are typically used in
the treatment, specifically 689 nm. Power levels as low as 0.5 watt are…

…specifically
689 nm. Power levels as low as 0.5 watt
are generally sufficient.
PDT is also used for wound healing,
although there is some debate about the
true efficacy of it for this purpose. Both
violet (405 nm) and near-IR (980 nm)
diode lasers are used in these…

Excimer lasers
Excimer lasers are another important
gas laser technology used in laser refractive surgical applications (LASIK). These
procedures use the unique deep ultraviolet
(193 nm) pulses from an ArF (argon fluoride) excimer laser to perform computercontrolled…
