Advanced Raw Material Al-50Si Alloys For MM Pump Combiner Substrates
Aug 13, 2018

Pump combiner is a passive component, built based on fused biconical taper (FBT) technique, widely used in fiber laser, fiber amplifier, high power EDFA, biomedical and sensor systems, etc.Tianjin Baienwei New Material Technology Co.,Ltd has vast experience to manufacture the Controlled Expansion AlSi alloy,e.g. AlSi70&AlSi50 sustrates products used for multimode(MM) pump combiner in fiber laser and high-power fiber laser applications. 

Advantages of Al-Si alloys:

  • ● low Coefficient and thermal expansion

  • ● high power transfer efficiency

  • ● RoHS compliance and ISO 9001 certified
