对空间色散方案中宽光谱带宽光的放大进行了分析和数值分析。结果表明，宽度接近荧光带宽的初始光谱可以在不变窄的情况下被放大，并且最初较窄的光谱在放大过程中可以显着加宽。导出了输出谱宽度的近似解析表达式，这对于构建超宽带放大器很有用。
The amplification of broad spectral bandwidth light in a spatially-dispersive scheme is analyzed both analytically and numerically. It is shown that an initial spectrum with a width close to the fluorescent bandwidth can be amplified without narrowing and the initially narrow spectrum can be broadened considerably during the amplification. An approximate analytical expression for the output spectral width is derived which could be useful in building ultrabroadband amplifiers.
