monochromaticity

With convolution integral, a new formulation for describing the relation of soft X-ray reflectivity of multilayer with the different energy Monochromaticity of incident light is deduced.

利用数学卷积积分,理论上推个在入射不同单色性下精确计算多层膜反射率的公式。

Laser is a new light source.Comparing with ordinary light the laser has good monochromaticity, directivity, coherency, high brightness, high power and high energy etc.
