Pulses in the CDPF are influenced alternatively by nonlinear effect and group velocity dispersion (GVD) effect in space and adiabatic optical soliton transmission can be maintained and evolved in anomalous dispersion region.
Also, in case [gamma] < 0 we have normal dispersion and in case [gamma] > 0 anomalous dispersion.
Third, we plan to demonstrate mid IR frequency combs using crystalline resonator and quantum cascade lasers: Crystalline resonators can due to their anomalous dispersion and large transparency generate low phase noise combs in the mid IR.
This phenomenon, when increasing the wave frequency slow rate decreases, called anomalous dispersion.
2(a), when the pump pulse with the wavelength of 785 nm and the average power of 300 mW polarize along the fast axis, the central wavelength of pump pulse lies on the positive slope of the PM-PCF dispersion profile in the anomalous dispersion region, and the soliton is formed due to the interplay between the negative dispersion and the self-phase modulation (SPM).
These include anomalous dispersion glass and large-diameter aspherical lenses, as well as the vendor's latest broadcast lens coatings, which reduce ghosting and flare.
These curves show an anomalous dispersion relation for different values of selection parameters.
Then they used X-ray crystallography, including a technique called molecular replacement with single-wavelength anomalous dispersion, to determine the structure and interaction of the two parts.
To start with, the pulse alters the properties of each section of the pathway so that it exhibits what's known as anomalous dispersion.
Chymosin is many times larger than any molecule whose structure had previously been determined without the use of isomorphous replacement, molecular replacement or anomalous dispersion, and the map demonstrates the potential of maximum-entropy methods in macromolecular structure determination.
The phases for structure determination were obtained using a combination of three experiments: Pt multi wavelength anomalous dispersion (MAD), BR MAD, and Xe single wavelength anomalous dispersion (SAD).
