Gas Laser

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.

4. How Gas Lasers Work starts with the excitation of the gas 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.

5. Applications of Gas Lasers 01 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.
