    • 1280nm 7mW SLD Laser Diode

    The 1280nm SLD series is a broadband SLD operating in inherent superluminescent mode. Unlike traditional ASE-based SLEDs, which produce narrower spectral bandwidths under higher drive currents, this superluminescent characteristic enables it to generate wider spectral bandwidths at higher drive currents. Its low coherence reduces Rayleigh backscattering noise. Combined with high power and broad spectral width, it mitigates photodetector noise, improving spatial resolution (for OCT) and measurement sensitivity (for sensors). This 1280nm SLD features a 14-pin butterfly package and meets the requirements of Bellcore document GR-468-CORE.

    Product features：High-power SLD output; Polarization-maintaining fiber coupling; Broad spectral characteristics; High stability; Compact industrial design

    Part Number：MP-SLD-1280-7-A81-14BF-PA

    Application area：Optical Coherence Tomography | Fiber-optic sensing | Device testing | Biological detection | Fiber-optic gyroscopes
