100s of kW Peak Power Fiber Amplifier for Next-Generation LiDAR Application

Based on our proprietary award-winning fiber laser technology, AdValue Photonics proposes an enabling fiber amplifier technology for the proposed NASArsquo;s next-generation topographic LiDAR mapping applications. This technology can easily be extended from the near-infrared spectral region to the visible green region via nonlinear frequency doubling, benefitting future hydrographic LiDAR mapping applications. In the Phase I program, we have preliminarily demonstrated the feasibility of such a high-peak-power Yb-doped fiber amplifier, and developed a preliminary mechanical design to package the amplifier system with two different cooling mechanisms. In the Phase II program, we will experimentally demonstrate this enabling technology by developing a compact deliverable prototype laser/amplifier unit that can generate 100s of kW peak power and gt;150W average power of nearly transform-limited spectral linewidth. By the end of the Phase II program, a prototype amplifier unit will be delivered to NASA Goddard Space Flight Center for evaluation test.
