Modulation-free pump-probe spectroscopy of strontium atoms.

Javaux, C. and Hughes, I.G. and Lochead, G. and Millen, J. and Jones, M.P.A. (2010) 'Modulation-free pump-probe spectroscopy of strontium atoms.', European physical journal D., 57 (2). pp. 151-154.


We have performed polarization spectroscopy on the 5s21S0 →5s5p1P1 transition of atomic strontium. The signal is generated by saturation effects, rather than optical pumping, as the ground state is non-degenerate. This technique generated a dispersion-type lineshape suitable for laser stabilization, without the need for frequency modulation. The dependence of the amplitude and gradient on intensity and magnetic field were also investigated, and compared to a related technique based on the circular dichroism induced by a magnetic field.
