A fiber spool with ultra-low vibration sensitivity has been demonstrated for the ultra-narrowlinewidth fiber-stabilized laser by the multi-object orthogonal experimental design method, which can achieve the optimization object and analysis of influence levels without extensive computation. According to a test of 4 levels and 4 factors, an L 16 (4 4 ) orthogonal table is established to design orthogonal experiments. The vibration sensitivities along the axial and radial directions and the normalized sums of the vibration sensitivities are determined as single objects and comprehensive objects, respectively. We adopt the range analysis of object values to obtain the influence levels of the four design parameters on the single objects and the comprehensive object. The optimal parameter combinations are determined by both methods of comprehensive balance and evaluation. Based on the corresponding fractional frequency stability of ultra-narrow-linewidth fiber-stabilized lasers, we obtain the final optimal parameter combination A3B1C2D1, which can achieve the fiber spool with vibration sensitivities of 10 −12 /g magnitude. This work is the first time to use an orthogonal experimental design method to optimize the vibration sensitivities of fiber spools, providing an approach to design the fiber spool with ultra-low vibration sensitivity.
A novel ‘‘green’’ solvent to deeply purify quartz sand with high yields: A case study
Xiaoxia Li,Tihai Li,Jianxiong Gao,Houquan Huang,Linbo Li,Jingsheng Li 한국공업화학회 2016 Journal of Industrial and Engineering Chemistry Vol.35 No.-
A novel ‘‘green’’ solvent for removing iron and aluminum impurities simultaneously from quartz sandwas presented to replace the outdated industrial strong acids. The solvent is a ‘‘green’’ mixturecomprised nontoxic, renewable acids and a very diluted hydrochloric acid. The new solvent cansignificantly reduce the pollution caused by residual acids and remain the high efficiency in removingimpurities and is harmless to the target product as well. The final optimum removing rate was up to79.1% and 42.3% respectively if its leached residue was washed, then leached again in a 4 g/l Na2CO3solution under ultrasound for 25 min.
