Absorbance spectra of the samples including the Fresnel reflections. The samples’ thicknesses are indicated in Table II.
Kerr shutter signal versus delay time between pump and probe laser pulses. (a) Signal corresponding to sample D for different pump and probe intensities. Open squares: , ; open circles: , ; and open triangles: , . (b) Normalized signal measured at the same pump and probe laser intensities. Open squares: (cell length: 1.0 mm). Open triangles: sample B. Open circles: sample C (Laser wavelength: 800 nm).
Normalized Z-scan transmittance profiles for samples A (solid circles) and D (open circles). (a) NL refraction (closed aperture configuration) (b) NL absorption (open aperture configuration). The curves were shift by 0.2 in the vertical scale to prevent overlap. Laser wavelength: 1064 nm.
Samples compositions and characteristic parameters ( is the glass transition temperature, is the linear refractive index, and is the linear absorption coefficient).
NL parameters measured ( is the NL refractive index and is the NL absorption coefficient).
Experimental results and theoretical predictions with basis on the BGO model (Ref. 25).
