TL;DR: In this paper, a simple method is demonstrated for high-order harmonic generation with fully controlled (linear, elliptical and circular) polarization, which potentially has a broad range of applications from ultrafast circular dichroism to attosecond quantum optics.

TL;DR: The rapidly decreasing microscopic single-atom yield, predicted for harmonics driven by longer-wavelength lasers, is compensated macroscopically by an increased optimal pressure for phase matching and a rapidly decreasing reabsorption of the generated X-rays, making tabletop, fully coherent, multi-keV X-ray sources feasible.

TL;DR: In this paper, a sparsity-based single-shot subwavelength resolution coherent diffractive imaging (CDI) method was proposed to reconstruct sub-wavelength features from far-field intensity patterns at a resolution several times better than the diffraction limit.

TL;DR: A method of performing single-shot sub-wavelength resolution Coherent Diffractive Imaging (CDI), i.e. algorithmic object reconstruction from far-field intensity measurements, applicable to objects that are sparse in a known basis.

TL;DR: The prospects for future ultrafast fiber lasers built on new kinds of pulse generation that capitalize on nonlinear dynamics are discussed, focusing primarily on three promising directions: mode-locked oscillators that use nonlinearity to enhance performance; systems that useNonlinear pulse propagation to achieve ultrashort pulses without a mode-lock oscillator; and multimode fiber lasers that exploit nonlinearities in space and time to obtain unparalleled control over an electric field.
