Lichtverstärkung
Lichtverstärkung, also known as light amplification, refers to the process by which the intensity of light is increased. This is typically achieved through stimulated emission, a fundamental principle behind lasers. In a medium capable of light amplification, incoming photons with the correct energy can trigger the emission of identical photons from excited atoms or molecules. This process leads to a cascade of photons, all with the same wavelength, phase, and direction, resulting in a coherent and amplified beam of light.
The core components for light amplification include an active medium, a source of energy (pumping mechanism),
This phenomenon has numerous applications across science, technology, and medicine. Lasers, which rely on light amplification,
