As they increase the output power, laser manufacturers face challenges such as thermal instabilities or nonlinearities that reduce the laser overall stability and reliability. Luckily, Stimulated Raman Scattering (SRS) effect can be overcome by using the RSS – Raman Scattering Suppressor within the lasers. This reduction of SRS greatly contributes to increasing the laser engines’ output, by improving their reliability and by enabling better power output stability. The RSS also allows laser manufacturers to use smaller core fibers, hence improving both pointing stability and power spatial distribution.
Now compatible with large core fibers for MOPA configurations and small fiber cores for highly single mode lasers.
TeraXion’s proprietary FBG manufacturing process allows for a wide reflection bandwidth and low-loss reflectors, resulting in reduced non-linear effects and highly effective lasers.

Top 5 Features
Value
Enables otherwise unachievable levels of output power consistency and beam quality stability. It also enables the use of much longer fibers, which are becoming essential to manufacture larger workpieces, and to give design flexibility for modular designs of multi-kilowatt systems.
Reliability
Patented design enabling unmatched handling of deleterious SRS. With very consistent performances and quality, long-term stable operation is ensured.
Power scaling
Suitable for fiber laser oscillators and MOPA up to 5 kW, creating a protection for power amplifiers. Eliminating SRS also means more margin to manage Transverse Mode Instabilities (TMI).
High efficiency
Minimizes energy down-conversion to the Stokes wave, with very low insertion loss.
Adaptability
Every laser design is different, and the RSS can be tailored to perfectly match the specific requirements of the system.
