Progress towards Direct Photoassociative Formation of Ultracold KRb Molecules in the lowest rovibronic state $X\,^1\Sigma^+, v=0, N=0$

POSTER

Abstract

We report our progress on direct formation of ground-state KRb molecules with $v$=$N$=0 using the resonant coupling of the $1\,^1\Pi$ and $2\,^1\Pi$ states just below the lowest excited asymptote (4$s$(K) + 5$p_{1/2}$(Rb)) as discussed in [1]. The molecules are formed in a dual species MOT by photoassociation using a cw titanium sapphire laser and then detected by resonance-enhanced multiphoton ionization using a pulsed dye laser. As a first step, we are continuing to assign the photoassociation spectrum reported in [2] using additional information from vibrational-state-selective detection. This research is supported by the National Science Foundation and by the Air Force Office of Scientific Research.\\[4pt] [1] W. C. Stwalley \textit{et al.}, J. Phys. Chem.
