The photoinduced variations of the on-axis transmittances versus the peak laser intensity at 1064 nm for the oxidized porous silicon PS-ox in cuvette with: a CaCl₂ (drying); b saturated H₂O vapor (wetting). The sample exposition for drying was: 0 h black curve, 1 h red, 2 h green, 3 h blue, 120 h – purple; for wetting: 120 h + 20 min dark yellow curve, +1 h wine, +24 h violet
