Abstract

We present a technique for single-beam measurement of the optical nonlinearity in GaAs for photon energies above the bandgap. We measured the real and the imaginary parts of the nonlinear refractive index of a bulk crystal by using the change in reflection of dye laser pulses (10 ns, 538 nm). The values obtained, n 2 = (7.8 ± 0.6) × 10-8 cm2/W and κ2 = (-2.8 ± 0.7) × 10-8 cm2/W, are discussed.
