Through analyzing the different between the theoretical equation and the experiments equation, the main reason is that the scalar crystal field parameter of a given host has the different Nv value for the different ions.
理论计算与实验拟合存在差异,分析了出现差异的原因,认为差异主要是由相同晶体场对于不同掺杂离子的影响即晶体场参数Nv值不完全相同而引起的。
it is shown that the width of the spectral degree of coherence can be larger, less than or equal to the corresponding width of spectral density, which depends not only on the scalar coherence length of the beams, but also on the truncation parameter.
结果发现,依赖于光束的标度相干长度和截断参数,光谱相干度的宽度有可能大于、等于或者小于对应的谱强度的宽度。
