9xxnm Series pump laser module
High-efficiency pump laser sources with in-house chips and 100% independent control. The high-performance 9xxnm pump LD provides fiber-pigtail output up to 800mW, with uncooled options. The 9xxnm pump laser is a semiconductor laser operating at 900+nm. It supplies energy to erbium ions (Er³⁺), promoting outer electrons to higher energy states for optical-signal amplification. High power, high stability and low noise make it a key component in fiber communications systems.
