Abstract
A laser is a device that amplifies light and produces a high directional, high intensity beam that has
a very pure frequency or wavelength. It comes in sizes ranging from approximately one tenth the
diameter of a human hair to the size of a very high powers ranging from 10ˉ9
to 1020 Watt and in the
wavelength ranging from the microwave to the x-ray spectral regions with corresponding
frequencies from 1011 to 10ˉ11 Hertz. Lasers have pulse energies as high as 104
Joule and pulse
durations as short as 6×10ˉ15sec.They can easily drill holes in the most of durable materials and can
weld detached retinas within the human eye.
