## Abstract We present experiments on two‐photon excitation of ^87^Rb atoms to Rydberg states. For this purpose, two continuous‐wave (cw)‐laser systems for both 780 nm and 480 nm have been set up. These systems are optimized to a small linewidth (well below 1 MHz) to get both an efficient excitatio
