Laser Beam Machining Ppt Online

In a typical atom, electrons reside in a ground state. When energy is applied (pumping), electrons jump to an excited state. In a laser medium, a "Population Inversion" is created where more atoms are in an excited state than in the ground state. When a photon passes by, it stimulates an excited electron to drop to the ground state, releasing another photon identical to the first. This chain reaction creates the high-intensity beam.

If you don't want to build from scratch, many educational sites offer a free . However, beware of outdated slides (e.g., those still claiming fiber lasers are "new"). Laser Beam Machining Ppt

To create a compelling , one must understand the source of the beam. The word LASER is an acronym for Light Amplification by Stimulated Emission of Radiation . In a typical atom, electrons reside in a ground state
