Abstract

We demonstrated that the dispersion of scanning microscope optics (including a Zeiss 40x/1.2 Apochromat objective) can be compensated by means of chirped mirrors over a bandwidth of 170 nm at 800 nm. The interferometric autocorrelation trace recorded at the focus of the microscope objective with a two-photon diode indicated a pulse duration of < 12 fs. The propagation time difference of the system can be minimized by proper choice of the components, enabling sub-12-fs pulse delivery with a completely filled 40x/0.8 Zeiss Achroplan water immersion objective.
