## Abstract We present experiments on twoβphoton excitation of ^87^Rb atoms to Rydberg states. For this purpose, two continuousβwave (cw)βlaser 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
The high-resolution two-photon absorption spectrum of the % 'A, (000) +3po 'Z 7 (000) system in NO1 shows rotational fine structure characteristic of a bent-to-linear transition. This structure is well tit by a simple Hamiltonian incorporating an upper state rotational constant B,.=O.419 +O.OOl cm-'
