ASE light source is a high stable, high outpt power broadband light source. The new generation of ASE sources have no high frequency ripples, which makes them very useful for sensor interrogation applications. These broadband light sources have desktop or min size module package. Fiber-Mart provides C-band, C+L band and broadband ASE. These are available with either a flattened spectral output for demanding applications, or a non-flattened response for less demanding or cost-sensitive applications. A range of output powers are available.
