| 摘 要： | 根据简单的计算模型，导出辐射能量谱形状因子和相干谐波辐射表达式，用此表达式讨论了不对称光学速调管的相干谐波辐射；对于合肥储存环相干谐波自由电子激光，提出了一个不对称光学速调管相干谐波辐射的研究方案，并且作了详细的计算，结果表明在较高的电子束能量下，调整光学速调管和外激光参数，使辐射段波荡器的辐射基波与外激光的二次谐波共振，进行相干谐波产生实验，能获得109量级相干加强因子。

| Abstract: | According to a simple calculation model, both the power spectrum formula and the coherent harmonic radiation formula are derived. With these formulae, the coherent harmonic radiation of asymmetrical optical klystron configuration is discussed. For the storage ring coherent harmonic FEL in Hefei, a method of the coherent harmonic radiation of asymmetrical optical klystron configuration is investigated, and the detailed calculation results are given. Thus adjusting the parameters of optical klystron and outer laser makes the resonant wavelength of radiation section to equal to the second harmonic wavelength of outer laser, and the coherent strengthen factor 10 9 can be acquired. |

| Keywords: | coherent harmonic radiation optical klystron energy modulation coherent strengthen factor density modulation |
