钛宝石可调谐飞秒激光器 TiF-DP系列
钛蓝宝石飞秒振荡器与直接二极管泵浦(DPSS Ti:S飞秒激光器)。该系统被设计为放大器系统的种子振荡器，以及超快光谱实验室和集成到第三方设备的OEM的基本启动解决方案。
TiF-DP系统是一种新型钛蓝宝石飞秒激光振荡器，其活性介质直接由激光二极管组件的发射泵浦。这种结构在保持传统DPSS激光泵浦系统输出光束质量、脉冲持续时间和长期输出功率稳定的同时，显著降低了成本。平均输出功率达到200mw，足以将TiF-DP系列系统作为有足够空间的放大器系统的种子激光源，并应用于众多科研应用中。该激光设计具有刚性整体热稳定体，并确保长期输出功率稳定漂移低于0.5% rms。
激光系统可以为三种主要输出脉冲持续时间选择之一进行工厂优化:20、30或50秒(根据特殊要求100秒)。一般规律是输出功率和调谐范围宽度的可达值随输出脉冲持续时间的增大而增大。
