## Introduction to High Power Continuous Fiber Laser
In recent years, high power continuous fiber lasers have emerged as a game-changing technology in various industries. With their exceptional precision, efficiency, and versatility, these lasers have revolutionized industrial applications, offering unprecedented levels of performance and reliability.
## How High Power Continuous Fiber Lasers Work
High power continuous fiber lasers operate on the principle of stimulated emission. They utilize an active fiber doped with rare-earth elements, such as erbium, ytterbium, or neodymium, as the gain medium. When an external energy source, such as a pump diode, excites the atoms within the gain medium, it triggers the emission of coherent light at a specific wavelength.
The continuous wave (CW) nature of these lasers allows for a steady and uninterrupted emission of laser beams, enabling precise and controlled material processing. The high power output of these lasers, typically ranging from kilowatts to multi-kilowatts, ensures efficient and rapid material ablation, cutting, welding, and marking.
