ASE erbium-doped

Product Details

ASE erbium-doped fiber light source module is a high-performance broadband light source developed based on the principle of semiconductor laser-pumped rare earth-doped fiber to generate spontaneous emission light using local optical feedback control technology.  It has the advantages of output power , low self-coherence, good symmetry of Gaussian spectrum, low polarization, good temperature and spectral stability in the full temperature range, etc., which can meet the increasingly strict requirements of ASE erbium-doped light sources in the fields of sensing, testing and imaging. The performance requirements are key components of high-sensitivity fiber optic sensors with high sensitivity and low noise.

Features:

High output power

High stability at full temperature center wavelength

Good optical power stability at all temperatures

Gaussian spectrum has good symmetry
