Laser materials processing requires high throughput without sacrificing stability or yield. As power increases, thermal instability and nonlinearities reduce reliability. Shengjia's Raman-scattering suppressor eliminates stimulated Raman scattering during fiber-laser signal transmission, increasing laser-engine output and resistance to back reflections. It also permits smaller cores to reduce transverse mode instability (TMI), improving pointing stability and spatial power distribution.
