509nm High power single frequency Laser

The 509 nm single-frequency continuous-wave (CW) laser represents a breakthrough in high-power, ultra-low noise laser technology. Utilizing an advanced injection-locked DFB seed laser combined with an external cavity Pound-Drever-Hall (PDH) resonant frequency doubling system, this laser breaks the record with an unprecedented 101.3 W output power and an ultra-narrow linewidth of 21 kHz. It serves as the ideal, high-performance pump and excitation source for cutting-edge quantum and precision engineering applications.

3W Fiber-Optic Raman Sodium-Doped Laser

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.
