Physicist Wolfgang Ketterle and his colleagues have demonstrated for first time that a condensate of sodium atoms travels in waves. In theory, these waves can be focused to produce an 'atom laser.'

Unlike an ordinary, incandescent bulb, a laser produces light of a single wavelength. Moreover, the emitted light waves are coherent, meaning that all of the energy peaks and troughs are precisely in step.

Now, a team at the Massachusetts Institute of Technology has demonstrated experimentally that a cloud consisting of millions of atoms can also be made coherent. Instead of flying about ...
