IdealPhotonics' pump combiner is a specialized fiber optic device that enables efficient coupling of multiple pump beams. It combines multiple pump lasers (e.g., 915/976nm) with low-loss (<0.5dB) insertion into the gain fiber using fused taper or microlens arrays, significantly improving the pump efficiency of fiber lasers/amplifiers (coupling efficiency >95%). It is suitable for kilowatt-level high-power laser systems.The "multi-pump high-brightness combining" technology, through heat-resistant fiber bundle design (power tolerance >500W/fiber) and low-loss fused taper technology (insertion loss <0.3dB), achieves efficient coupling of 3-7 pump beams (brightness conservation rate >90%), directly powering the pump module of 10,000-watt fiber lasers and becoming the core energy engine for industrial cutting/welding equipment.
