Fiber Bragg Grating Products
YESWEHAVE Fiber Bragg Gratings (FBGs) are precision fiber-optic components for wavelength selection, optical filtering, laser cavity control, and dispersion management. Designed for both CW fiber lasers and ultrafast laser systems, our FBGs include standard and customized configurations for applications such as high-power fiber laser cavities, narrow-linewidth lasers, pulse stretching, and dispersion control. With customizable center wavelength, bandwidth, reflectivity, and grating characteristics, FBGs provide flexible all-fiber solutions for demanding photonics applications.
Why Use Fiber Bragg Gratings?
1. CW Fiber Laser Cavities
Used as high-reflectivity (HR) gratings and output couplers to define the laser cavity and control the operating wavelength.
2. Ultrafast Laser Systems
Chirped FBGs provide controlled dispersion for pulse stretching in Chirped Pulse Amplification (CPA) systems, helping prepare ultrashort pulses for amplification and subsequent compression.
3. Wavelength & Spectral Control
Provides selective reflection or transmission for precise control of the laser spectrum.
4. Low-Loss All-Fiber Integration
Can be directly spliced into fiber-based systems, eliminating free-space alignment and enabling compact, stable all-fiber architectures.
5. Customized Optical Performance
Grating parameters such as center wavelength, bandwidth, reflectivity, and dispersion can be tailored to specific laser architectures.
