Fiber Bragg Gratings (FBGs) are crucial components in fiber lasers, revolutionizing laser technology. FBGs are periodic variations in the core of an optical fiber that act as selective filters, reflecting specific wavelengths of light while allowing others to pass through. This unique property makes them invaluable in fiber laser systems.
FBGs are essential in fiber lasers, enabling wavelength selectivity, stability, and tunability. They shape the laser emission spectrum, maintain coherence, and facilitate precise control, driving advancements in fiber laser technology and opening up a wide range of applications across industries.
