Abstract
Resolution sufficient to resolve second-order Doppler broadening (3.9 kHz) has been obtained for the Ca 1S0–3P1 transition (657 nm) by using an atomic beam and optical Ramsey fringe techniques. Laser-beam separations up to 21 cm yield Ca linewidths (HWHM) as narrow as 1 kHz. As resolution is increased to approach, then exceed, the second-order linewidth, large asymmetries, shifts, and shape changes occur in the Ramsey fringe profile.
