Highly excited $S$ , $D$ , and $F$ levels in cesium and rubidium have been populated utilizing a two-step optical excitation method. In the first step an rf lamp is used to transfer atoms into the first $P$ states, and the subsequent excitation is performed with the tunable radiation of a cw dye laser.

Production of large numbers of atoms in a selected excited state by laser optical pumping: calcium

Thomas J. Mcilrath, John L. Carlsten

An experiment is described in which large numbers ( approximately 10 16 ) of calcium atoms are placed in the 4s4p 3 P metastable level by optical pumping with a tunable dye laser and then studied spectroscopically. Equations governing the degree of excitation by the laser are derived. Predictions of the theory are shown to be in good agreement with experimental results. In particular, at low optical depths produced by 10 15 ground state atoms cm -2 the dye laser raises approximately 50% of the calcium atoms into the metastable state. At higher optical depths associated with 10 17 ground state atoms cm -2 the number of excited states is limited only by the laser energy and line width. For the dye laser used the largest number of metastables produced was approximately 10 16 . The absorption spectra of the 4s4p 2 P level is seen out to 4s4p 3 P to 4s22d 3 D. The relaxation rate between the excited state fine structure is studied directly with an optically delayed dye laser continuum. Other applications of this technique of producing large numbers of excited states are briefly discussed.An experiment is described in which large numbers ( approximately 10 16 ) of calcium atoms are placed in the 4s4p 3 P metastable level by optical pumping with a tunable dye laser and then studied spectroscopically.

Pulsed dye laser for excitation of strontium

Priya Gupta

This thesis describes the construction and characterization of a high energy, tunable, pulsed dye laser that is used to make ultracold strontium plasma. In order to make ultracold plasma, we cool and trap strontium atoms in a magneto-optical trap (MOT) and then photoionize them with the dye laser. The dye laser is pumped by high-energy 355nm pulses from a commercial Nd:YAG laser and it gives out 10ns pulses of 400--415nm light with up to 50mJ/pulse. We will discuss the lasers spectrum, wavelength calibration, output power and efficiency for photoionizing strontium.This thesis describes the construction and characterization of a high energy, tunable, pulsed dye laser that is used to make ultracold strontium plasma.
