Laser tecnology

Laser Technology
Laser technology is used
in almost every scope of
life, from the miniscule
lasers in CD players to
the lasers used to scan
groceries in the checkout
line to the massive lasers
in aeronautics design.
The discovery of laser
technology and the
subsequent building of
ever-improving lasers
have benefited the
human race
tremendously,
particularly through
medical advances.
Medical lasers cause
medical procedures to be
quicker, better, and
easier than their
traditional counterparts.
The only drawback is
increased cost.
In 1917, Albert Einstein
was the first person to
suggest the basics of
what would become
lasers, by discussing the
theory of Stimulated
Emission, which is a type
of electron transition in
which a photon is
emitted from an atom
causing a chain reaction
with other atoms to
repeat the action. In
fact, the word laser is an
acronym for Light
Amplification by the
Stimulation Emission of
Radiation. Charles
Townes, an American
physicist, further
developed the idea with
microwave (invisible)
light in the mid- to
late-50's and Theodore
Maiman built the first
working optical (visible)
light laser in 1960.
Improvements and
variations on hundreds of
kinds of lasers continue
to be made since the
1960s. Those involved in
quantum mechanics have
been studying some form
of lasers, either in theory
or in reality, since the
1920s. Uses for laser
technology are
widespread and are
included in such
important fields as
medical/surgery,
communications, design,
manufacturing/industry,
and research.
Medical/Surgery
The advancement of
medical lasers has vastly
improved the ease and
success of surgery. The
cost, however, is greater
than that of other
treatments, though
scarring is much less with
lasers and lasers work
much more quickly than
older surgical options.
Incisions are more
precise and easier to
control. Some medical
areas in which lasers
have deeply refined
treatment options are in
laser eye surgery,
oncology, neurosurgery,
cardiology, dermatology,
veterinary surgery, and
dental surgery.
Communications
Televisions, telephones/
cellular phones, and
computer systems all
benefit from the use of
lasers. Lasers are able to
carry the huge amounts
of channels and
frequencies required by
these high-tech devices.
Lasers have proven the
best communication
device to have in the
space age.
Design
Lasers have transformed
the world of design by
making it possible for
designers to perform
with precision that was
previously unavailable.
Lasers are used to design
digital and three-
dimensional objects with
much more ease and
accuracy through
scanning, cutting,
copying, and digital
archiving. From designing
a building to designing
landscape, lasers prove
to be the best option for
fast and easy design.
Manufacturing/Industry
Lasers have improved the
manufacturer's ability to
produce tenfold. For
example, with a laser
cutter, a clothing
manufacturer can have
fabric patterns cut much
more quickly and more
accurately in no time. A
jeweler has much more
precision on his side
when employing lasers to
work on fine gems.
Airplane designers can
construct an aircraft
much more efficiently
and with greater results
using laser technology.
Research
The use of lasers in
research enables
scientists to uncover
much more detail and
detect very slight
movement when studying
matter. The lasers can be
tailored to only respond
to certain colors or
movements and, in that
way, they provide much
more specialized work in
research environments.
The world of laser
technology is always
expanding by producing
new applications and
ways to benefit people.
The dependence that the
modern culture has on
lasers is amazing
considering that it was
not prevalent until the
past forty years.
