Examplesofrefractive

refractive
Here we restrict ourselves to quantify the strength of the thermal lensing and hence fit a parabola to therefractiveindex profiles.
From theCambridge English Corpus
However, at the intensity maxima, the self-focusing effect is masked by the saturation effect of the nonlinearrefractiveindex.
From theCambridge English Corpus
These are mica flakes 0.5pm thick, 5-20pm diameter, coated with titanium dioxide to raise theirrefractiveindex.
From theCambridge English Corpus
These results investigate various illustrations given for therefractiveindex, power threshold, and self-focusing lengths as a function of laser intensity and density.
From theCambridge English Corpus
The second acoustic mode, with a phase velocity less than the thermal velocity, is found to be evanescent (refractiveindex purely imaginary).
From theCambridge English Corpus
In the case of ducted waves, the plasma inhomogeneity is arefractivewaveguide for fast magnetosonic waves.
From theCambridge English Corpus
Spectacle lenses alter eye growth and therefractivestatus of young monkeys.
From theCambridge English Corpus
The cell width increased very slowly, and therefractiveindex gradients decreased, but the effects were still observable many days later.
From theCambridge English Corpus
Such arefractiveindex profile will tend to focus the pulse, preventing the natural diffraction and keeping the laser pulse confined in the channel.
From theCambridge English Corpus
The beam thus creates arefractiveindex profile across its wavefront corresponding to its own intensity profile and focuses of its own.
From theCambridge English Corpus
Such an effect competes with the usualrefractiveones, and plays a crucial role in plasma diagnostics, radio-frequency heating and current drive experiments.
From theCambridge English Corpus
Refractiveerrors were evaluated during rearing in all subjects.
From theCambridge English Corpus
Consequently, therefractiveindex is not uniform in that region too.
From theCambridge English Corpus
It is of degree 2 + 3s in the square of therefractiveindex if s is the number of different particle species.
From theCambridge English Corpus
On all illuminated points of one pattern, therefractiveindex was a near-maximum, while on the other it was a near-minimum.
From theCambridge English Corpus
