Principle

The fiber optic amplifier made of doped rare-earth elements brings a revolutionary change to the light wave technology. Through appropriate feedback mechanism, any Light amplifier could be laser, therefore the fiber optic laser development could based on optical fiber amplifier, The current fiber optic lasers mainly use doped rare-earth elements fiber as gain medium, due to the fiber core of fiber optic laser is very small, high-power density can be easily formed within the optical fiber under the action of the pumped light, resulting in laser energy level "population inversion" of the working-laser materials. Therefore, laser oscillation can be formed by appropriately adding the regenerative circuit (to form a resonant cavity).
