We present a faster repumping scheme for strontium magneto-optical traps operating on the broad 5s^{2}^{1}S_{0}−5s5p^{1}P_{1} laser cooling transition. Contrary to existing repumping schemes, we directly address lost atoms that spontaneously decaye

A steady-state magneto-optical trap (MOT) of fermionic strontium atoms operating on the 7.5-kHz-wide ^{1}S_{0}-^{3}P_{1} transition is demonstrated. This MOT contains 8.4×10^{7}atoms, a loading rate of 1.3×10^{7}atoms/s, and an average temperature

Bose-Einstein condensates (BECs) are macroscopic coherent matter waves that have revolutionized quantum science and atomic physics. They are essential to quantum simulation and sensing, for example underlying atom interferometers in space and ambitio

We report on our progress towards a continuously-operating active optical clock on the 3 P 0 → 1 S 0 transition of neutral 87 Sr or 88 Sr atoms. Our approach is based on a ring-cavity in which an optical conveyor carries a continuous stream of atom

A continuous guided atomic beam of $^{88}\mathrm{Sr}$ with a phase-space density exceeding $10^{-4}$ in the moving frame and a flux of $3 \times 10^{7} \, \mathrm{at \, s^{-1}}$ is demonstrated. This phase-space density is around three orders of magn

We determine the frequency of the ultranarrow $^{87}\mathrm{Sr}\phantom{\rule{4pt}{0ex}}^{1}S_{0}\ensuremath{-}^{3}P_{2}$ transition by spectroscopy of an ultracold gas. This transition is referenced to four molecular iodine lines that are observed b

We demonstrate a continuously loaded $^{88}\mathrm{Sr}$ magneto-optical trap (MOT) with a steady-state phase-space density of $1.3(2) \times 10^{-3}$. This is two orders of magnitude higher than reported in previous steady-state MOTs. Our approach is
