Nufern's 30/250 Ytterbium-doped double clad Fiber is specifically designed for short pulse amplification where fiber length is a critical design factor because of very high peak powers. The high absorption enables very short fiber amplifier lengths without sacrificing efficiency. Short pulse fiber amplifiers can be considered low-costreplacements for Nd:YAG lasers used in materials processing, LIDAR and range finding applications. This 30/250 Large Mode Area fiber is available in both a standard and a PANDA-style PM format. Nufern also offers alternate versions of these fibers with higher Yb dopant concentration.
