德国Layertec有一款用于校正、调整飞秒脉冲的GTI色散啁啾镜，GTI是Gires-Tournois interferometers的缩写，因此也叫做Gires-Tournois干涉镜和GTI反射镜。GT干涉镜型号众多，波长覆盖350-1590nm，反射率最高达到99.99%，GDD值是1800-10000fs²。另外，GTI镜的选择需要从波长，反射率，应用等方面考虑。
自1996年以来，德国Layertec一直为欧洲研发机构和激光制造商等生产啁啾反射镜和GTI镜。在几百份关于短脉冲激光技术发展的科学出版杂志中，Layertec作为定制部件的供应商被提名。Layertec镜片主要是根据波长、反射率以及应用来选择合适的镜片。Layertec反射镜种类繁多，主要产品有纳秒/皮秒/飞秒激光镜片，低色散激光镜片、激光输出耦合镜、啁啾镜和GT干涉镜等。其中GTI色散啁啾镜波长覆盖紫外（350nm）到近红外(1590nm)，反射率高达到99.99%，GDD值是1800- -10000fs²。
GT干涉镜英文名称是Gires-Tournois interferometers，也叫做Gires-Tournois干涉镜、GTI反射镜和GTI镜。其中，为了增加脉冲功率或高重复率，可以通过使用多个具有相位校正的GTI反射镜来实现所需的校正，另外GTI镜还能够用来优化其他波长。当然，在选型上，用户需要明白波长、反射率、入射角、GDD以及应用等参数，当这些参数都能够确定，就能够快速选择出需要的产品。
Gires-Tournois干涉镜（GT干涉镜）参数规格库存表：
下面是GTI反射镜和啁啾镜的参数规格以及库存情况，用户可以根据自己特定的需求从表格中选择需要的产品，GTI镜不仅只有标准品，还可以根据用户需求进行定制。
