VLMA Er Amplifier
Development of the new Very Large Mode Area Erbium Doped Fiber Amplifier Module was driven by increasing demand for high energy and high peak power pulses for a wide variety of industrial and scientific applications.
The VLMA Amplifier Module builds upon the TrueMode™ Fiber Laser Cavity family designed for kilowatt single-mode fiber lasers for industrial machining and welding. Lightera, a global market leader in the design and manufacture of rare-earth doped fibers, possess the expertise and experience in fiber fabrication necessary to meet that demand. Lightera has been developing and manufacturing high-power components and modules for many years and understands the reliability standards expected in the diverse material processing applications.
