We report a challenging design, fabrication and post-production characterization problem of a dispersive mirror supporting the spectral range from 2000 nm to 2200 nm and providing a group delay dispersion of -1000 fs. The absolute reflectance in the working range is over 99.95%. The reported mirror is a critical element for Tm and Ho based lasers and paves the way for the development of ultrafast 2 µm lasers with sub-100 fs pulse duration.
我们报告了一个具有挑战性的色散镜设计、制造及后期表征问题，该色散镜支持2000纳米至2200纳米的光谱范围，并提供-1000飞秒的群延迟色散。工作范围内的绝对反射率超过99.95%。所报道的镜子是基于铥和钬的激光器的关键元件，为开发脉冲持续时间低于100飞秒的超快2微米激光器铺平了道路。
