Abstract

We have determined the potassium penetration cross-section in chemically tempered glasses by nondestructive nonlinear refraction measurements. The nonlinear refraction as a function of the depth was measure by the Nonlinear Ellipse Rotation (NER) signal using ultrafast laser pulses (40 fs, 1 kHz, ~2000 GW/cm² at 780 nm) from an amplified laser system. For local NER measurements, we have used a long distance objective (20x, 1.5 cm WD) which provides a relatively good penetration resolution (~5.5 microns). We characterized several glasses with different ion exchange treatment time. The potassium penetration depth and cross-section could be correlated with the materials’ hardness.
