低群延迟色散反射镜

低群延迟色散反射镜（Low GDD Ultrafast mirror)是欧洲进口的低群延迟色散超快反射镜，它专业为飞秒激光应用而设计，通过精心选择镀膜膜系，提供高反射率和低GDD性能，非常适合Ti:S激光，钕玻璃激光，而玻璃激光，掺Yb激光使用。

Low GDD Ultrafast mirrors are designed for femtosecond applications to provide an optimized performance at certain wavelength and angle of incidence (AOI). This is achieved by careful selection of coating stacks to combine high reflectivity and low GDD value (from -10 fs2 to 10 fs2 at design bandwidth) at the same time. Such coatings are used for external beam manipulation applications where pulse broadening effect is undesirable. Low GDD Ultrafast mirrors are intended for Ti:Sapphire, Nd:Glass, Er:Glass or Ytterbium doped host based lasers working in femtosecond regime. Variety of catalogue components allows to choose the right mirror for fundamental wavelength as well as for harmonics.

	Other dimensions and wavelengths are available in small and mass production quantities
	GDD values ranges from -10 fs2 to 10 fs2 at design bandwidth
