摘要：
The narrow 12.5 mum, 5d2D3/2-5d2D5/2 fine-structure transition in a laser-cooled, single Ba+ atom has been probed with a tunable sideband from a frequency-stable (NH3)-N-15 laser operating on the sP(8, 6) transition. Single-ion Doppler-free resonances with negligible time dilation shift are observed without any detected motional sidebands for each Zeeman component. Linewidths of 11 kHz are observed for the components, which are currently limited by the probe laser frequency excursions. A measurement of the D-D transition center frequency relative to the sP(8, 6) saturated absorption dip has been performed. A preliminary measurement of the sP (8, 6) line center frequency gives the line center for the Ba-138+ isotope transition as 24 012 048.5 +/- 0.2 MHz.
