  Time-like linear dilaton backgrounds admit a classical solution that
describes a closed folded string that is created at an instant. We refer to
such strings as Instant Folded Strings (IFS). We study an exact worldsheet CFT
description of an IFS that involves two vertex operators which describe two
open string modes that propagate on a time-like FZZT-brane, which plays the
role of a regulator to the IFS. We take advantage of this description to
calculate the most basic quantity associated with IFSs - their production rate.
Some implications of this calculation to stringy cosmology and black hole
interior are briefly discussed.
