Our Single-Frequency Fiber Amplifiers are designed to provide optical gain across a broad range of wavelengths while maintaining the integrity of narrowband, single-frequency signals.

These amplifiers are optimized to deliver high output power for narrowband sources, ensuring excellent performance without triggering Stimulated Brillouin Scattering (SBS). These modules may also be paired with a second-harmonic generation (SHG) module to efficiently convert NIR light into visible light.

Designed to amplify single-frequency signals without triggering SBS, Large variation of wavelengths, High output power, Diffraction-limited fiber or collimated beam output.
