实验表明减法运算放大器增益带宽是硬件方法的关键。
Experiments showed that the gain-bandwidth of the subtracting operational amplifier is the key of hardware method.
但是，如果系统中色散波较大，放大器增益的微调量也相应较大。
But if larger dispersion wave exists in system, the enhancing of PSA's gain must be larger.
分析了喇曼光纤放大器的泵浦光源个数、波长、功率等因素对放大器增益平坦度的影响。
The influences on the gain flatness of the Raman fiber amplifier by the number of pumps, wavelength, power and other factors are also analysed.
