In this presentation we are discussed some basics about Gas LASER, it's types and how it's work. I mentioned some advantages and disadvantages of gas LASER.

2. Gas Laser :
*The gas lasers ,are lasers that use a gas medium for the
amplification of light .
*In gas laser, the active medium that produces this light is a
gas or mixture of gases.
*Their invention in the 1960.

Carbon Dioxide Lasers
Argon-ion Lasers

atoms. This is typically achieved
through an electrical discharge,
which boosts the atoms to a higher
energy state. The excited atoms
then decay to a lower energy state
by emitting photons. If these
photons encounter another excited
atom, they can stimulate the atom
to emit more photons of the same
energy, direction, and phase – this is
the ‘stimulated emission’
mentioned earlier. These photons
are then reflected back and forth
between mirrors, which form a
resonant cavity, amplifying the light
and producing the laser beam.

Industry
High-power gas lasers
like the CO2 laser are
ideal for material
processing tasks such
as cutting and
welding.
02
Medicine
gas lasers are used for
a variety of
procedures including
laser surgery, skin
treatments, and eye
surgery.
03
Scientific Research
They are used in
spectroscopy,
holography, and even in
large-scale experiments
like particle
acceleration.
04
Telecommunications
Some gas lasers,
especially helium-neon
lasers, are used in fiber-
optic communication
systems.

9. Advantages
• high efficiency
• ability to produce a high-
quality beam
• excellent spatial coherence
• offer a wide range of output
wavelengths
Disadvantagses
• they often require high
voltages to operate
• gas refill can be expensive
and complicated.
• some gases used in these
lasers can be hazardous.
