If a particular color or wavelength of light hits the ytterbium when it is in the excited state this light will be a aplined, generating a carbon copy of the original light. In this way a very lower perfect beam can be amplified many times to produce high power beam that are nearly perfect and are therefore very focusable.
如果一种特殊的颜色或光线的波长击中 Yb ,而此时正是激发状态时,这种特殊颜色的光线将被放大产生高能量的近乎完美而且有聚焦能力的光束。

The results showed that (1) The grain size of nanometer YiO_2 was40~80nm.The wavelength corresponding to the maximum absorbency values were observedin the 200~320nm range.The crystal structure of carbon doped TiO_2 photocatalyst is primarilyanatase(22.43% rutile), and the content of carbon is about 4.6%.(2) The relative humidityvaring from 8% to 80%, the photocatalytic degradation degree of benzene increased withincreasing relative humidity; and to toluene, degradation rate was hanced by relative humidityup to 60%, and more or less inhibited above 60%.(3) Scheme and results of orthogonal testswere used by evaluating the photocatalytic performance of the gas phase methanol, acetoneand 1-heptane.The results revealed that their degradation degree reached 84.5%, 93.39% and93.45%, respectively.(4) The 254nm UV lamp showed higher photocatalytic degradation rate.For methanol, acetone and 1-heptane, it was found that photocatalytic degradation reactionoccurs with the light strength of daylight lamp.(5) Under the the same conditions, 15%degradation degree has been obtained for benzene, whilst about 10% degradation degree wasattained by Degussa P25; During the initial phases, the toluene revealed higher photocatalyticactivity, comparing with Degussa P25, the degradation degree of methanol, acetone and1-heptane were slightly lower.
