We report the measurement of Kerr nonlinearity of thin films of GaN by using the eclipsing Z-scan technique. The measurement was performed using 100 fs pulses at 800 nm. We measured a pure refractive signal, whose associated nonlinear Kerr coefficient was n(2) = (-7.3 +/- 0.4) x 10(-14) cm(2) W-1.

Abstract
We report the measurement of Kerr nonlinearity of thin films of GaN by using the eclipsing Z-scan technique. The measurement was performed using 100 fs pulses at 800 nm. We measured a pure refractive signal, whose associated nonlinear Kerr coefficient was n(2) = (-7.3 +/- 0.4) x 10(-14) cm(2) W-1.File in questo prodotto:
