| Description: |
A purple laser beam slows erbium atoms (the purple beam traveling right to left) emerging from an oven at 1300°C, in preparation for trapping and cooling. The unusual properties of erbium atoms and the new capability to trap them could lead to development of novel technologies.
*PHY, erbium, laser trapping, semiconductors, telecommunications, laser cooling, atom trapping
