摘 要: | 研究表明,进入Wiggler场的相对论电子束的发散角增大,将降低自由电子激光器的增益,但小量的发散角可提高激光器的输出功率。最大容许的发散角由激光振荡条件决定。

Effect of electron beam divergence on free-electron laser output |
| |
Abstract: | Our research shows that when the divergence of reiativistie electron beam entering into the wiggler increases, the gain of the free-electron lasers will be decreased and a small divergent angle will increase the output power. The maximum allowable divergent angle is determined by the laser oscillation conditions. |
