超快光谱

使用我们的超快激光器在飞秒或皮秒时间尺度上研究相关过程，或利用宽带宽输出应用于2D应用中。

性能和稳定性 在获得短脉冲宽度和可靠的稳定性方面绝不妥协。
操作简便性 选择一体化激光器/放大器或通过开放平台尽可能的提高灵活性。
全天候可靠性 = 生产力 通过避免意外停机，尽可能提高可发布数据输出量。

研究超速流程

超快激光脉冲使研究各种材料中的瞬态过程成为可能。许多这类研究都使用某种类型的泵浦探测方法，其中一个脉冲激发样品，而另一个脉冲分析结果。这是因为与超快激光脉冲令人难以置信的时间分辨率相匹配的优异工具是另一个超快激光脉冲！因此，有些实验装置相当复杂。这就是为什么我们在所有超快激光器中都强调简单性和可靠性，这样您就可以将所有精力放在实验上而非激光器上。
