Because of the effects of self-mixing interference, the spectrum linewidth of laser will be squeezed or unfolded. 在反馈存在的情况下,激光器光谱线宽可能变窄或变宽,这可以被应用于激光器线宽的压榨。
Normally, the measured spectral line for the superheated iron atoms would show up as a symmetrical peak. 通常,所测得的超高温铁原子光谱线会显示出一个均匀的尖顶。
A particular spectrum line corresponds to a certain definite light wavelength. 某特定的谱线就代表一个确定光的波长。
In astronomical situations, the natural line width is seldom directly observed. 在天文学研究中,谱线固有宽度很少能直接观测到。
