  The stationary light pulse (SLP) refers to a zero-group-velocity optical
pulse in an atomic ensemble prepared by two counter-propagating driving fields.
Despite the uniqueness of an optical pulse trapped within an atomic medium
without a cavity, observations of SLP so far have been limited to trapping a
single optical pulse due to the stringent SLP phase-matching condition, and
this has severely hindered the development of SLP-based applications. In this
paper, we first show theoretically that the SLP process in fact supports two
phase-matching conditions and we then utilize the result to experimentally
demonstrate simultaneous SLP trapping of two optical pulses for the duration
from 0.8 $\mu$s to 2.0 $\mu$s. The characteristic dissipation time, obtained by
the release efficiency measurement from the SLP trapping state, is 1.22 $\mu$s,
which corresponds to an effective Q-factor of $2.9\times 10^9$. Our work is
expected to bring forth interesting SLP-based applications, such as, efficient
photon-photon interaction, spatially multi-mode coherent quantum memory,
creation of exotic photonic gas states, etc.
