broad-band spectrum

基本解释

In order to broad amplifying band, it is important to modify spectrum properties of erbium-doped optical fiber.
为得到更宽放大带宽，最主要的是改变掺杂光纤的光谱性能。
A flat and ultra-broad-band SC spectrum is obtained by optimizing the fiber parameters and the peak power, pulse width of pump pulse.
通过对光纤色散斜率的优化设计并综合考虑泵浦脉冲功率、脉冲宽度对SC谱谱宽和平坦度的影响，获得了平坦、超宽的SC谱。
Filter is used to transmit spectrum of definitive broad band in the continuous spectrum or to extract certain radiation in the line-spectra.
光学滤光片在连续的光谱中用于透过一定宽度的光谱带或在线状光谱中提取某些辐射。
