A second-order susceptibility χ(2) is created by the thermal poling method in a bulk sample of Ga5Ge20Sb10S65 sulfide chalcogenide glass. We present experimental results focusing on the time-evolution properties of the created nonlinear layer. By cycling the poling operation on a sample, the generated second harmonic signal is improved, and the second-order nonlinearity is shown to be stable over several months. The χ(2) susceptibility profile is carefully reconstructed and its maximum value reaches 4-5 pm/V.
