We report an intense near-infrared pump, c-axis terahertz probe measurement on an electron-doped cuprate superconductor Pr0.88LaCe0.12CuO4 with Tc = 22 K. The major effect of the intense pump is to induce a splitting of Josephson plasma edge below Tc, similar to the observation on hole-doped cuprate La1.905Ba0.095CuO4 in a superconducting state. The photoexcitation induced spectral change does not exhibit significant decay up to the longest measured time delay 210 ps. Furthermore, the result suggests that the intense near-infrared pump drives the system from a superconducting state with a uniform Josephson coupling to a metastable superconducting phase with modulated Josephson coupling strengths below Tc.
