We investigated linear-cavity with ultra-low repetition rate Erbium-doped fiber laser mode-locked by a high modulation depth SESAM. Output pulses were highly-chirped, at energy up to 14 nJ and minimum repetition rate was 25 kHz.
A 91.4 kHz repetition rate Er-doped dispersion managed mode-locked fiber laser was demonstrated. The pulse energy was amplified to 790 nJ though single stage amplifier.

A novel 6-DOF parallel manipulator composed of two limited-DOF manipulators is proposed in this paper, the degree of freedom (DOF) of this manipulator is analyzed and the position kinematic modeling is established. The Jacobian matrix is derived by vector loops equations. The workspace is determined considering the interference check by the numerical method. Furthermore, the performance of the mechanism is evaluated according to dexterity criteria. In order to satisfy the different configuration requirements, the two reconfigurable structures are presented based on the presented 6-DOF parallel mechanism. The work provides basis for the development of the novel robotic manipulator.

In this paper, a hybrid method is developed to real-timely solve dynamic problems governed by second partial differential equation (PDE). The present method involves the combination of reduced-basis method (RBM) and implicit Newmark's method. In this method, it needs a training space, which contains the solutions corresponding to some carefully selected sample parameters and all time steps. A greedy algorithm is adopted to adaptively select basis vectors from the training space for constructing reduced basis space. It results in a reduced system by the standard Galerkin projection the matrices and loading vector. The solutions in arbitrary new parameters are approximately regenerated by solving the reduced Newmark's formulas. To further enhance the efficiency, an off-line/on-line decomposition is suggested for the computational implementation of the method. The present method is applied to analysis the transient response in an actual functionally graded material (FGM) plate. In comparison, the computational cost of transient displacement analysis in FGM plate is reduced significantly. The numerical example demonstrates the efficiency and accuracy of our algorithm.
