摘要： A tensioning device and method for post-tensioning a concrete member having at least one crack is provided. The tensioning device may include an elongated body, a stitch catch arm and an anchor. The catch arm may be perpendicularly joined to one end of the elongated body, wherein the catch arm is inserted into a hole in the concrete member. The elongated body may form an anchor recess therein, wherein an anchor interface surface is defined by the anchor recess. The anchor interface may form an anchor aperture for receiving the anchor. The thickness of the anchor interface may uniformly decrease as the anchor interface extends toward the catch arm end of the anchor recess so that when ratcheting the anchor into the concrete member and onto the anchor interface a portion of the applied compressive force and/or torque may be transformed into an axial force along the elongated body so as to provide post-tensioning through the tensioning device and across the at least one crack.

摘要： A pulsed fiber array laser system that has actively stabilized coherent beam combination (CBC) is disclosed. The active stabilization is accomplished using both piston phase control and intra-pulse phase control, allowing a much greater increase in pulse energy. Further stabilization using intra-pulse amplitude control is also disclosed. A chirp profile can be written on the output pulse to enable specific applications. An amplitude profile of the amplifier array may optionally be tailored to match to a reference electrical pulse. Using the current invention, a much smaller number of amplifier chains will be needed to achieve certain pulse energy, resulting in a system with lower complexity, lower cost, smaller size, less weight, and higher reliability.
摘要翻译：公开了一种具有主动稳定的相干光束组合（CBC）的脉冲光纤阵列激光系统。主动稳定是使用活塞相位控制和脉冲内相位控制来实现的，允许脉冲能量增加更多。还公开了使用脉冲内幅度控制的进一步的稳定化。可以在输出脉冲上写入啁啾曲线，以实现特定应用。可以可选地调整放大器阵列的幅度分布以匹配参考电脉冲。使用本发明，需要更少数量的放大器链来实现某些脉冲能量，从而导致具有较低复杂性，较低成本，较小尺寸，较小重量和更高可靠性的系统。
