| 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). Advantages 1 Low Cost 2 Long using life of laser device 3 Small size, maintenance-free 4 Low operating environment requirement. 5 Fine beam quality Output Features Compared with semiconductor laser, the advantages of fiber optic lasers lie in: fiber optic laser adopts waveguide structure, accommodable to strong pump and has high gain, high efficiency, low threshold, the output beam quality, line width, simple structure and high reliability features, easy to implement and fiber coupling. |
