Self-Synchronous Coherent Beam Combination [PDF]
2006 Digest of the LEOS Summer Topical Meetings, 2006 A completely novel concept for coherent beam combination is presented. The technique completely eliminates the need for a reference beam resulting in a dramatic simplification of electronic coherent beam combination without any compromise in performance.

Advanced Engineering Materials, EarlyView.Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

A coherently combined laser beam for lidar
Acta Physica Sinica, 2011 A fundamental way to improve the ability of lidar to detect the small target far away is to increase the light intensity on it, and the coherent combination of laser beams is an effective way to obtain a large intensity on the target. A parameter named combining effect factor is introduced to evaluate the combining effect on small target. On this basis,

Advanced Engineering Materials, EarlyView.CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.
