Spectroscopy of calcium on an atomic vapor — •Lukas Möller, David Röser, Frederik Wenger, Andreas Reuß, Anica Hamer, and Simon Stellmer — Physikalisches Institut, Universität Bonn

Calcium is an element that posseses multiple desireable qualities that make it suitable for a multitude of applications, including atomic clocks and the search for beyond standard model physics. All of these applications are based on high precision spectroscopy. Spectroscopy on thermal atomic vapor is a straightforward and well-estabished method. By applying a lock-in detection scheme that uses both frequency and amplitude modulation to saturated absorption spectroscopy, we measure the isotope shifts of the 423-nm 1S0 -> 1P1 transition for all stable calcium isotopes.

Keywords: calcium; saturation spectroscopy; isotope shifts; lock-in; thermal atoms
