    "abstract": "We propose and analyze the possibility of performing two-photon\ncontinuous-wave Doppler-cooling of hydrogen atoms using the 1S-2S transition.\n\"Quenching\" of the 2S level (by coupling with the 2P state) is used to increase\nthe cycling frequency, and to control the equilibrium temperature. Theoretical\nand numerical studies of the heating effect due to Doppler-free two-photon\ntransitions evidence an increase of the temperature by a factor of two. The\nequilibrium temperature decreases with the effective (quenching dependent)\nwidth of the excited state and can thus be adjusted up to values close to the\nrecoil temperature.",
