Welcome to the OFSCN® Technical Inquiry forum.

The topic mentioned covers the OFSCN® Laser Fiber Bragg Grating (Bare), which serves as the critical resonator mirrors for fiber lasers. These components are designed to provide high-reflectivity or specific output coupling within a laser cavity.

Technical Overview of OFSCN® Laser FBGs

OFSCN® Laser Fiber Bragg Grating (Bare) are typically used in pairs: a High Reflector (HR) and an Output Coupler (OC) to form the laser resonator.

Key Technical Specifications:

  • Operating Wavelengths: Standard options include 1064nm and 1080nm, with a customizable range from 1510nm to 1590nm.
  • Bandwidth: Standard Full Width at Half Maximum (FWHM) is typically 0.5nm or 0.2nm.
  • Reflectivity:
    • HR (High Reflector): >99.5%
    • OC (Output Coupler): Customizable between 1% and 90% depending on the laser design.
  • Fiber Types: Available in Single Mode (SM), Double Clad (DC), or Polarization Maintaining (PM) fibers to match various fiber laser architectures.

Application Mapping

These gratings are essential for:

  1. Fiber Laser Resonators: Creating stable laser oscillation at precise wavelengths.
  2. Wavelength Locking: Ensuring narrow-line width output for semiconductor lasers.
  3. Optical Filtering: High-precision spectral selection in high-power systems.
