Abstract: We give the first construction of covariant coherent closed string states,which may be identified with fundamental cosmic strings. We outline therequirements for a string state to describe a cosmic string, and using DDFoperators provide an explicit and simple map that relates three differentdescriptions: classical strings, lightcone gauge quantum states and covariantvertex operators. The naive construction leads to covariant vertex operatorswhose existence requires a lightlike compactification of spacetime. When thelightlike compactified states in the underlying Hilbert space are projected outthe resulting coherent states have a classical interpretation and are inone-to-one correspondence with arbitrary classical closed string loops.
