| Popis: | We have compared two kinds of dispersive mirrors (DMs) produced by magnetron sputtering and ion beam sputtering. One of them is a broadband DM which is known as double-angle DM, providing a group delay dispersion (GDD) of $$-40 \mathrm{{fs}}^2$$-40fs2 in the range of 550–1050 nm. The other one is a robust highly dispersive mirror, which provides a GDD of about $$-275 \mathrm{{fs}}^2$$-275fs2 at 800 nm and covers the wavelength range from 690 to 890 nm. For the first time, a comparison between magnetron-sputtering-produced and ion-beam-sputtering-produced dispersive mirrors is performed. |
