Implication

Experimental study demonstrates single-beam z-scan technique for measuring nonlinear refractive index across multiple materials, indicating high phase-distortion sensitivity.

Key Points

To introduce a sensitive single-beam experimental technique for measuring both the sign and magnitude of the nonlinear refractive index n(2).
Translated samples along the propagation (z) direction of a focused Gaussian laser beam at a fixed pulse energy.
Measured far-field optical transmittance through an aperture using pulsed CO2 and Nd:YAG laser sources.
Far-field transmittance plotted against sample position produces a characteristic dispersion-shaped curve directly yielding the sign and magnitude of n(2).
Achieved high sensitivity where a 1% change in optical transmittance corresponds to an optical phase distortion of approximately lambda/250.
