REUS钛宝石再生放大器系统
特点:
紧凑一体设计
脉冲能量>3 mJ/1 kHz
可以升级到更高能量
<40 fs脉宽
光束质量好
良好的光束指向性和长时间功率稳定性
Regulus RA系列放大器由飞秒种子振荡器(TiF-15F3或光纤EFOA-SH),展宽器,法拉第旋转器,具有控制器和同步器的普克尔盒,再生放大器,脉冲放大器的泵浦激光器和压缩器组成。系统可以装配额外的普克尔盒,用于改进对比度。使用普克尔盒,用户可以得到“要求的脉冲”,降低重复频率至需要的值。所有的元件集成到一个箱体中,固定在一个厚面包板上,具有可靠性和稳定性,无需进行手动操作。根据客户要求,添加多级多程功率放大(重复频率减小到10或15 Hz)系统可以升级到每脉冲500 mJ。
Regulus RA放大器系列是飞秒微加工系统,太赫兹成像,OPA泵浦,远程遥感和超快光谱技术的理想光源。
