TeraXion’s all-fiber PowerSpectrum™ DMR chirped fiber Bragg gratings (FBG) provide precise compensation for either anomalous or normal dispersion for mode-locked ultrafast lasers.  The DMR has especially high dispersion accuracy and is compatible with most mode-locked laser configurations for a range of customizable wavelengths and cavity lengths.

Mode-locked ultrafast fiber lasers have replaced most of their solid-state counterparts because of superior ruggedness, easier miniaturization, and simpler integration. TeraXion is a pioneer in designing and manufacturing chirped FBGs for ultrafast fiber lasers. After a decade of refinement, the PowerSpectrum™ DMR is unmatched in the industry for meeting the demanding requirements of femtosecond pulse generation.

  • Advanced knowledge of high-accuracy dispersion management
  • Manufacturing process that minimizes phase ripples
  • Production methods that yield results closely matched to theoretical design
