A new technique to investigate the spatial distribution of the reflection spectrum along fabricated long weak fiber Bragg gratings (FBG) is experimentally demonstrated, together with its potential applications for distributed fiber sensing and broadband si ...
We present a technique for in situ visualization of the biomechanics of DNA structural networks using 4D electron microscopy. Vibrational oscillations of the DNA structure are excited mechanically through a short burst of substrate vibrations triggered by ...
Ultralow densities of crystalline nanospheres have been detected in amorphous polymer microspheres by utilizing the unique sensitivity of second-order nonlinear optical techniques to anisotropy. Vibrational sum frequency scattering (SFS) and X-ray diffract ...
In this paper, the design and implementation of a femtosecond-resolved ultrafast transmission electron microscope is presented, based on a thermionic gun geometry. Utilizing an additional magnetic lens between the electron acceleration and the nominal cond ...
A method for performing magnetic resonance spectroscopy on solid sample containing nuclei of interest with spin quantum number I, comprising: subjecting the sample to a static magnetic field, spinning the sample at the magic angle and broad-band excitation ...
We present a study on THz generation in lithium niobate pumped by a powerful and versatile Yb:CaF2 laser. The unique laser system delivers transform-limited pulses of variable duration (0.38-0.65 ps) with pulse energies up to 15 mJ and center wavelength of ...
No adequate treatment currently exists for bilateral vestibulopathy, which can result in significant decreases of social and physical functioning. To improve patients' quality of life, vestibular neuroprostheses are being developed. Efficacy of current pro ...
High-energy terahertz pulses are produced by optical rectification (OR) in organic crystals 4-dimethylamino-N-methyl-4-stilbazolium tosylate (DAST) and 4-N,N-dimethylamino-4'-N'-methyl-stilbazolium 2,4,6-trimethylbenzenesulfonate (DSTMS) by a Ti: sapphire ...
Femtosecond laser processing of glass has been proven to be an efficient tool for fabricating waveguides and microchannels. Here we show that monolithic integration in bio-Micro- Electro-Mechanical-Systems can be pushed forward by introducing additional fu ...
Controlling magnetization dynamics with a femtosecond laser is attracting interest both in fundamental science and in industry because of the potential to achieve magnetic switching at ever faster speeds. Here, we report a coherent, phase-locked coupling b ...
