Such optics can be made on base of metal or dielectric coatings covering a spectral range 200-3000 nm. Both options are possible with Helios and Syrus machines. Below one can find four examples of high-quality multilayer mirrors produced with Helios and Syrus. The examples can be considered as a guide for MAP researchers.
A complementary pair of 1.5-octave UBCMs for the spectral range 400-1200 nm (picture 1). Such a pair supports sub-3-fs pulses. GDD at 800 nm is -20 fs2, average reflectivity 98 %.
