Toward Quantum Degeneracy in Strontium
ORAL
Abstract
We present recent work toward achieving quantum degeneracy in Strontium. A MOT operating on the strong ($\Gamma $= (2$\pi $ )* 32 MHz), $^{1}$S$_{0}$ $\rightarrow ^{1}$P$_{1 }$transition cools 2.5*10$^{8}$ atoms to 2 mK in the first stage of cooling. Then, approximately 40{\%} of these atoms are transferred to a MOT operating on the weaker ($\Gamma $= (2$\pi $ )* 7.5 kHz) $^{1}$S$_{0 }\rightarrow ^{3}$P$_{1}$ intercombination transition, further cooling the sample to 5 $\mu $K. Here we discuss transferring this sample to a dipole trap and using evaporative cooling techniques to reach quantum degeneracy.
