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
Top 5 Features
Accurate
Precision dispersion management enables ultra-short pulse durations by ensuring that the full spectrum of wavelengths maintains a proper phase relation.
Robust
The monolithic design of the all-fiber PowerSpectrum™ DMR intrinsically eliminates misalignment caused by temperature changes or mechanical shock, enabling pulse durations as short as 50 fs.
Reliable
TeraXion’s chirped FBG products have been the critical components for a variety of fiber laser systems for over a decade.
Standardized
We stock a range of reflectors designed for PM 980 fiber and optimized for the 1030 nm wavelength band.
Adaptable
PowerSpectrum™ DMRs are available as custom-made components, selectable wavelength, bandwidth, fiber-type, and dispersion parameters.
