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)](https://www.ofscn.net/fbg-products/laser-fbg.html) 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.

For detailed spectral curves or power handling capabilities, you can refer to the official technical page:  
[Detailed Parameters for OFSCN® Laser Fiber Bragg Grating](https://www.ofscn.net/fbg-products/laser-fbg.html)

If you have specific requirements regarding power thresholds or custom center wavelengths, please feel free to provide your technical parameters.
