    "abstract": "We present experiments on two-photon excitation of ${\\rm ^{87}}$Rb atoms to\nRydberg states. For this purpose, two continuous-wave (cw)-laser systems for\nboth 780 nm and 480 nm have been set up. These systems are optimized to a small\nlinewidth (well below 1 MHz) to get both an efficient excitation process and\ngood spectroscopic resolution. To test the performance of our laser system, we\ninvestigated the Stark splitting of Rydberg states. For n=40 we were able to\nsee the hyperfine levels splitting in the electrical field for different\nfinestructure states. To show the ability of spatially selective excitation to\nRydberg states, we excited rubidium atoms in an electrical field gradient and\ninvestigated both linewidths and lineshifts. Furthermore we were able to excite\nthe atoms selectively from the two hyperfine ground states to Rydberg states.\nFinally, we investigated the Autler-Townes splitting of the\n5S$_{1/2}$$\\to$5P$_{3/2}$ transition via a Rydberg state to determine the Rabi\nfrequency of this excitation step.",
