As €˜eye-safe’ LiDAR applications continue to proliferate, the need for high efficiency and reliable fibers capable of delivering high pulse energies and good beam quality becomes critical. Coherent offers a family of high-performance Erbium/Ytterbium doped single and double clad fibers. These fibers are optimized to achieve record efficiencies in the 1.5µm wavelength range while suppressing parasitic 1µm Amplified Spontaneous Emission (ASE). By balancing the trade-offs between efficiency, power threshold, and 1µm ASE, Coherent offers the highest performance Erbium/Ytterbium-doped fibers available. Our product portfolio includes fibers with a variety of core sizes each optimized for the rigorous demands of a harsh environment and/or mobile LiDAR applications.
