• A second-order susceptibility χ ( 2 ) is created by the thermal poling method in a bulk sample of Ga 5 Ge 20 Sb 10 S 65 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.
