These Ho3+-doped germanate glasses have an advantage in the maximum of the absorption,emission and gain cross-sections compared with those of other reported glasses.

The effect of various gain coefficient on soliton-effect picosecond pulse compression in fibers with slowly decreasing dispersion;

The paper discussed the determining of gain coefficient α on line with the method of adaptive ESM during rolling process,proposed the idea of using parameter segment estimation method of unknown variance σ 2 in statistics to determine the credible probability.

The elementary exploration was conducted for the determination of gain factor a with exponential smoothin, for the adoptive control mathematical model in milling under steady condition.

At first, the gain factor(Γ) curve changing with the angle of incidence(θ) is gived, and a corresponding maxing angle of incidence(2θ=29.

In this paper,three-dimensional computational flow dynamic technology was applied on the research assessment device improvement chemical laser model by solving the laminar Navier-Stokes equations and transportation equations to study iodine molecule dissociation rate,iodine atom pumping rate,singlet oxygen yield rate and small signal gain distributions.

Three-dimensional CFD technology is applied in a RADICL model by solving laminar Navier-Stokes equations and transportation equations to study iodine molecule dissociation rate,iodine atom pumping rate,singlet oxygen yield rate and small signal gain at different flow rate ratio of primary and secondary flow.

The study on effective gain cross section shows that there is a flat gain shape between 1530～1580 nm, which proves that the wide-band property of the glass i.
