Efficiency of dispersive wave generation in dual concentric core microstructured fiber

, 2015
We describe the generation of powerful dispersive waves that are observed when pumping a dual concentric core microstructured fiber by means of a sub-nanosecond laser emitting at the wavelength of~1064 nm.

A novel dynamic scheme to reconstruct sub-50 atto-second pulses [PDF]

arXiv, 2018
The attosecond streaking technique is normally utilized to characterize the attosecond pulses in extreme ultraviolet spectrum, while the pulse simulation and reconstruction schemes turn out to be unreliable for extremely short sub-100as pulses.

Measurement of pressure dependent variations in local pulse wave velocity within a cardiac cycle from forward travelling pulse waves

Scientific Reports
The local pulse wave velocity (PWV) from large elastic arteries and its pressure-dependent changes within a cardiac cycle are potential biomarkers for cardiovascular risk stratification.

Phase Synchronization of Stimulated Raman Process in Optical Fiber For Long Pulse Regime [PDF]

arXiv, 2019
We investigate the evolution of coherence property of noise-seeded Stokes wave in short (< 1 ps) and long pulse (> 1 ps) regimes. Nonlinear equations expressing the evolution of pump and Stokes wave are solved numerically for both the regions. The simulations include quantum noise by incorporating noise seed in the pump field where one photon per mode ...

Identification and Reversible Optical Switching of NV+ Centers in Diamond

Advanced Functional Materials, EarlyView.
NV+ centers in diamond are predicted to coexist with NV0 and NV– centers, but direct experimental confirmation remains challenging. Using positron annihilation spectroscopy with in situ light illumination, a charge transition NV+/0 is observed at 1.234(8) eV.

Traveling waves in periodic metric graphs via spatial dynamics [PDF]

arXiv
The purpose of this work is to introduce a concept of traveling waves in the setting of periodic metric graphs. It is known that the nonlinear Schr{\"o}dinger (NLS) equation on periodic metric graphs can be reduced asymptotically on long but finite time intervals to the homogeneous NLS equation, which admits traveling solitary wave solutions.
