Sensitive measurement of optical nonlinearities using a single beam

A sensitive single-beam technique for measuring both the nonlinear refractive index and nonlinear absorption coefficient for a wide variety of materials is reported. The authors...

High-sensitivity, single-beam n_2 measurements

We present a simple yet highly sensitive single-beam experimental technique for the determination of both the sign and magnitude of n(2). The sample is moved along the z directi...

Two Photon Absorption, Nonlinear Refraction, And Optical Limiting In Semiconductors

Two-photon absorption coefficients /32 of ten direct gap semiconductors with band-gap energy Eg varying between 1 .4 and 3.7 eV were measured using 1.06 µm and 0.53 um picosecon...

Energy band-gap dependence of two-photon absorption

We present measurements of the two-photon absorption coefficients beta(2) of 10 different semiconductors having band-gap energies between 1.4 and 3.7 eV. We find that beta(2) va...

Optical switching and n2 measurements in CS2

Picosecond degenerate four-wave mixing studies in ZnSe

The degenerate four-wave-mixing technique has been applied using 30-ps FWHM pulses of 532-nm light output from a frequency-doubled Q-switched and mode-locked Nd:YAG laser. By in...
