Abstract
We improve the efficiency of sawtooth-wave adiabatic-passage cooling for strontium atoms in three dimensions and combine it with standard narrow-line laser cooling. With this technique, we create strontium magneto-optical traps with bosonic ( fermionic ) atoms at phase-space densities of (). Our method is simple to implement and is faster and more robust than traditional cooling methods.
