摘要
从一维自由电子激光理论出发,唯象地考虑衍射效应,计算和分析了光导效应的特点和规律;针对曙光一号装置的自由电子激光参数,利用二维理论对光场剖面、填充因子、光场半径等进行了数值模拟;根据计算结果分析和讨论了影响光导的因素和实验条件。
On the basis of one-dimensional FEL theory, we 'consider phenomenally diffraction effect of optical wave, calculate and analyse the characteristics and pattern of optical guiding .Using two-dimensional theory , we simulate optical field profile , filling factor , and optical field radius etc , according to SG-1 FEL parameters , and discuss some factors of effect on optical guiding and operational condition from these results .
