LD-PD PTE. LTD.'s Raman fiber laser is a high-performance all-fiber light source based on stimulated Raman scattering technology. Different from rare-earth doped fiber lasers, it realizes wide wavelength coverage from 1270 nm to 1370 nm, covering all major optical communication bands.
Equipped with wavelength-locked pump diodes and built-in precise TEC temperature control, the laser features narrow linewidth, low noise and no mode hopping. It achieves excellent beam quality with M²＜1.1 and superior long-term power stability. Optimized fiber design effectively suppresses SBS effect to support stable high-power output.
With compact structure and complete protection circuits, the product passes strict telecom reliability tests. Customizable fiber pigtails, wavelengths and output power are available. Widely applied in long-distance fiber communication amplification, distributed optical sensing, high-precision spectroscopy and biomedical microscopy, this Raman laser delivers stable, cost-effective photonics solutions for industrial and scientific research customers worldwide.
