광섬유 레이저 시스템의 작동 원리

The core of a fiber laser system is the optical fiber, which is doped with rare-earth elements. When pumped with a high-power diode laser, these elements emit photons that are amplified as they travel through the fiber. The laser beam is then focused and directed onto the workpiece using various optical components.

The process begins with the diode pump source, which provides the initial energy to excite the rare-earth ions in the fiber. As these ions return to their ground state, they emit photons that stimulate further emission, creating a cascade of light amplification. This process continues until a highly coherent and intense laser beam is produced.

Advantages of Fiber Laser Systems

1. High Beam Quality Fiber lasers produce a beam with excellent spatial and temporal coherence, allowing for precise and clean cuts, even on highly reflective materials.

2. Energy Efficiency Fiber lasers are significantly more energy-efficient than traditional CO2 lasers, converting a higher percentage of electrical energy into laser light.

3. Compact Design The use of optical fibers as the gain medium allows for a more compact and robust design, making fiber laser systems easier to integrate into existing manufacturing setups.

3. Additive Manufacturing Fiber lasers are increasingly being used in additive manufacturing (3D printing) processes, where they provide the energy needed to fuse metal powders layer by layer.

4. Microprocessing The high beam quality of fiber lasers allows for precise microprocessing tasks, such as drilling, cutting, and structuring, in the production of microelectronic components.

5. Medical Applications Fiber lasers are used in various medical applications, including laser surgery, dental procedures, and the manufacturing of medical devices.
