A new type of tunable stretcher for ultra-short pulses is presented based on silica wires with subwavelength-diameters. Through proper design of the diameters of wires and the refractive indices of surrounding environment, we obtain large second-order dispersion and small higher-order dispersion, which are beneficial for pulses broadening around the operation wavelength.
The spectral extension (peak line) is analyzed to determine the shift velocity (U_{mathrm{sft}}) and the frequency broadening around the peak line to determine the sweeping velocity (U_{mathrm{swp}}).
The second quantity is the frequency broadening around the dispersion relation for the mode m: begin{array}rcl@ Delta_{m} = frac{1}{Omega_{mathrm{p}}} leftlangle int_{omega_^{omega_ mathrm{d}omega left omega - f_{m} k_{perp}) right)^{2} E k_{perp},omega) rightrangle_{k_{perp}}, end{array} (3).
Central holds performing arts workshops in secondary schools in "lower-participation" areas, she says, which sounds like a great scheme, and apparently broadens interest around the UK.
By applying the model to a two-dimensional unsteady Reynolds averaged Navier Stokes flow computation, it is shown that the three-dimensional effects, like spectral broadening around the shedding frequency, are partially recovered.
The spectrum exhibits an extension with a peak line and a broadening around the peak line.
Akšamija's exhibition Design for a Nomadic World, featured in Amman Design Week, aims to broaden the dialogue around the role of design in conditions of conflict and crisis within a global perspective.
"In these difficult political times, I am fortunate to have actually broadened my support around the state and the nation due to the stances I have taken.
While the cultural conversation around motherhood has broadened vastly in the years since, Simpson's view on the wider position of women in society remains gloomy.
Group 3 portrayed a slightly broadened overall stress around the infraorbital foramen when compared to group 4 (Figure 7).
