• We report results of thermal poling experiments performed with continuous and alternating electric fields in Suprasil glass. Firstly, the second-order nonlinearity induced with a continuous voltage is fully characterized, and the nonlinear region is found to extend to almost 80 μ m under the anode surface. Then, we focus our study on experiments realized with a square alternating poling field. For particular frequencies in the millihertz regime, we found a 30 times increase of the generated second harmonic signal. The nonlinear layer created under these conditions is completely characterized and a χ ( 2 ) value of 0.3 pm ∕ V is reached for the first time in a Suprasil glass. This χ ( 2 ) coefficient is one order of magnitude greater than best results reported so far in Suprasil glasses.
