Study Notes
Ruby Crystal LASER Development
- Theodore Maiman is credited with the development of the first Ruby Crystal LASER in 1960.
LASER Acronym
- LASER stands for "Light Amplification by Stimulated Emission of Radiation."
Basic Processes in Laser Light
- Stimulated Emission: Excited electrons release photons, nurturing the amplification of light.
- Spontaneous Emission: Initially excited electrons drop to lower energy levels, emitting photons randomly.
- Absorption: Atoms absorb photons, moving electrons to higher energy states.
Energy Level Width
- The typical value of the width of an energy level, relevant to monochromaticity, is on the order of a few GHz or less.
Central Wavelength to Line Width Ratio
- The ratio of the central wavelength to the line width is termed the "quality factor" (Q-factor) and is indicative of the monochromaticity of the laser light.
