The PowerSpectrum RSS is an all-fiber, FBG-based unique bandpass filter that eliminates the Stimulated Raman Scattering (SRS) while transmitting the laser signal in high-power fiber lasers. It is the only cost-effective solution that eliminates the SRS at its source and enables immunity from back reflection from the work piece.

The laser material processing industry requires high throughput without sacrificing process stability to ensure high manufacturing yield. 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, they can overcome these by using  TeraXion’s PowerSpectrum™ RSS (Raman Scattering Suppressor to decrease the Stimulated Raman Scattering (SRS) effect within their lasers. This reduction of SRS greatly contributes to increasing the laser engines’ output, while improving their immunity to back reflections, improving their reliability and the general power output stability. The RSS also allows laser manufacturers to use smaller core fibers to lower thermal mode instabilities (TMI), hence improving both pointing stability and power spatial distribution.

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.
