TiF-SP激光系统在TiF系列的Ti:S飞秒激光振荡器中提供了最短的脉冲持续时间。它是用于尖端超快速研究的强大工具。
该系统可以作为独立版本提供,用于与外部泵浦激光器一起泵浦,也可以作为具有现场标准泵浦激光器的版本在现场或在我们的工厂中集成。但是,两种版本的Ti:S激光头的尺寸均相同,以后可以以最小的额外成本将独立版本的泵浦激光器集成到独立版本中。TiF-SP可接受的泵浦激光功率最高为10W。
该系统的设计目的是将24/7作为种子振荡器用于我们的大型放大器系统,从而继承了所有增强稳定性的设计功能。可以将系统预调至可用配置之一(12、15、30或40 fs),包装箱内的所有组件都相同,或者可以配备其他选件在这些范围之间切换。在这种情况下,光谱的中心波长调谐范围的宽度随着脉冲持续时间的增加而增加。
共有三个预先设计的工厂供应套件:
“手动”套件包括一个按钮式非自动电子启动器,并允许使用激光盒壁上的测微螺钉手动调节波长和脉冲持续时间设置。
“基本”工厂包装包括一个简单的USB电动波长调谐狭缝和一个按钮式非自动电启动器。使用此软件包进行波长调谐和校准是通过基本Windows软件中的步骤号信息完成的。
“自动”工厂软件包包括内置光谱仪和功率计,带有预设的单点触摸波长调谐,可配置的小部件软件,主动电源锁定功能以及自动模式锁定启动和监控。借助该软件包,该系统具有出色的长期稳定性和更长的不间断运行时间。
TiF-SP的整体式热稳定体为输出辐射参数提供了出色的被动稳定性。
也可以使用外部棱镜对或可调脉冲压缩器(APC-Pro或APC-Kit单元)进行输出脉冲线性调频补偿和预补偿。
