脉宽：<120 fs
波长：1240 nm
一体设计
>1 TW峰值功率系统
Cr:Forsterie飞秒放大器的FREGAT系列，基于新型工作物质，辐射1230-1240 nm 飞秒脉冲。系统含有脉冲展宽器，再生放大器，同步和延迟产生器，脉冲压缩器，带有光纤泵浦激光器的种子振荡器，以及放大泵浦激光器。
FREGAT-0TW系统在这个波长提供TW级的峰值功率。

* - up to 30 mJ upon request; also see the FREGAT-TW system (110 mJ); ** - depends on the amplifier pump laser; an additional pulse slicer may be added to the unit. This improves the contrast ratio and allows the repetition rate to be adjusted from single-shot to the maximum repetition rate of the amplifier. | |||
