Nonlinear refraction at the absorption edge in InAs

Optics Letters, 1984
The results of measurements of nonlinear refraction at the absorption edge in InAs between 68 and 90 K taken with an HF laser are compared with those of a band-gap resonant model in which the contribution of the light-hole band is included and found to account for more than 40% of the observed nonlinear refraction.

Nonlinear refraction in vitreous humor

Optics Letters, 1993
We extend the application of the z-scan technique to determine the nonlinear refractive index (n(2)) for human and rabbit vitreous humor, water, and physiological saline. In these measurements there were nonlinear contributions to the measured signal from the aqueous samples and the quartz cell that held the sample.

Nonlinear absorption and nonlinear refraction in HgCdTe

SPIE Proceedings, 1990
The large third order susceptibility of Hg1_CdTe makes it a very promising material for many applications, including optical switching. There have been numerous studies' 4) ofthe optical nonlinearities of Hg1_CdTe and it is well known that for values ofx near 0.2 and for 10.6 ,tm radiation, both nonlinear absorption arising from two photon absorption ...

Nonlinear refraction in CS2

Applied Physics B, 2004
The nonlinear refractive index (γ) of CS2 was measured using the Z-scan technique and laser radiation of various (femto-, pico-, and nano-second) pulse durations. We observed the growth of γ with the increase of the pulse duration (from (3±0.6)×10-15 cm2 W-1 at 110 fs to (4±2)×10-14 cm2 W-1 at 75 ns) due to the additional influence of the molecular ...

Nonlinear Absorption and Nonlinear Refraction Studies in MEBBA

Topical Meeting on Ultrafast Phenomena, 1984
In this paper we report measurements of nonlinear absorption and optical self-action (self-focusing) in 4-methyl benzylidene 4’-n-butylaniline (MEBBA) with picosecond pulses at 0.53 μm and 1.06 μm. P2, the second critical power for self-focusing [1], was measured as a function of pulsewidth (37 to 150 psec FWHM) and polarization state at 0.53 and 1.06 ...

Single-shot measurement of nonlinear absorption and nonlinear refraction

Applied Optics, 2006
A single-shot method for measurement of nonlinear optical absorption and refraction is described and analyzed. A spatial intensity variation of an elliptical Gaussian beam in conjugation with an array detector is the key element of this method. The advantages of this single-shot technique were demonstrated by measuring the two-photon absorption and ...

Nonlinear Absorption and Nonlinear Refraction of Self-Assembled Porphyrins

The Journal of Physical Chemistry B, 2006
Nonlinear refraction and nonlinear absorption of self-assembled porphyrins in the nanosecond and picosecond regimes were studied at 532 nm by the Z-scan technique. First, a marked difference in nonlinear refraction was observed between self-assembled zinc porphyrins and free base porphyrins; however, the effects of self-assembly and metallization on ...
