Laser Physics
- A laser is a device that emits light through optical amplification based on stimulated emission of radiation.
- LASER is an acronym for Light Amplification by Stimulated Emission of radiation.
Components of a Laser
- Gain medium: the material that emits light, can be a gas, solid, or liquid.
- Energy source: used to excite atoms or molecules in the gain medium.
How a Laser Works
- Excited atoms or molecules in the gain medium release photons of light.
- Photons emitted by stimulated emission are in phase, having the same frequency and direction.
- In a laser beam, light waves move in the same direction and at the same speed.
- The gain medium can be a solid, like glass, or a liquid.
- One mirror reflects light back toward the other, creating a cavity.
- Light is reflected back and forth in the cavity, amplifying it.
