The Comment proposes that the discrepancy between two second harmonic scattering (SHS) experiments for DO electrolyte solutions with 100 ns and 190 fs laser pulses is due to unexplained processes for 100 ns pulses that give non-quadratic power dependence for the second harmonic signal. However, the different power dependence of the second harmonic scattering signals measured with 100 ns and 190 fs laser pulses is due to changes in laser beam propagation and focal intensity caused by the combined effect of thermal defocusing and Kerr lens self-focusing. Non-quadratic power dependence does not explain the discrepancy in the second harmonic scattering results.
