远红外自由电子激光器脉冲结构
-
摘要: 采用整体数值模拟方法，研究了中物院远红外自由电子激光装置的起振和脉冲结构。给出了为克服激光呆滞效应起振所需的腔长失谐值，腔长调节精度和调节范围。预计了装置的增益、功率、脉冲宽度和谱线宽度等重要参量。研究了不同腔长失谐值下光脉冲结构的变化。Abstract: With an INEX model, the start up and the structure of optical pulse of CAEP FIR FEL are studied. To counteract the effect of lethargy, the necessary detaining of the cavity length, and precision and range for adjusting cavity length are given. The gain, power, pulse width and bandwidth are predicted. The pulse structure different cavity length is investigated.
