Continuous-wave measurement of the hydrogen 1S-2S transition frequency.
We have measured the 1S-2S transition frequency in atomic hydrogen with a precision of 7 parts in 1010 by continuous-wave Doppler-free two-photon spectroscopy. We employ cavity-enhanced multimilliwatt radiation near 243 nm produced by sum-frequency generation, and we observe the 1S-2S transition in...
