For organic polymer asymmetric rib waveguide, the fundamental mode cut-off conditions, the single-mode conditions and the polarization characteristics were studied systematically under different rib height, rib width, core height and the short side width of core slab by means of semi-vector finite-difference beam propagation method. The results showed that both fundamental mode cut-off area and the...
Many factors of intracavity perturbation will degrade the output power and beam quality for high power passive Q-switched slab laser. In the paper, the experiment test on the output beam quality of a passive Q-switched zig-zag slab Nd:YAG laser has been performed by adopting Hartmann-Shack (H-S) wavefront sensor and Zernike mode reconstruction theory, namely wavefront properties can be fully obtained...
This paper presents a hybrid strategy for the hot rolling scheduling problem, which is derived from the actual steel production. Some features such as the rolling length of the consecutive slabs with same width, temperature jump between adjacent slabs make the solution methodology more difficult. Therefore, the hybrid strategy is proposed to determine good approximate solutions for this complicated...
