An external-cavity semiconductor laser with nonlinear optical feedback to generate broadband chaos with time delay signature (TDS) suppression is investigated. The system is composed of three semiconductor lasers, one of which is regarded as the chaos gen
The influence of the different phase functions on the spatially resolved reflectance measurements is studied with Monte Carlo simulations. We show that the spatially resolved reflectance from a homogenous semi-infinite medium is mostly dependent on the se
The (2 1)-dimensional nonlinear Schrodinger (NLS) equation with spatially inhomogeneous nonlinearities is investigated, which describes propagation of light in (2 1)-dimensional nonlinear optical media with inhomogeneous nonlinearities. New types of optic
Laser polarization and its intensity inside a filament core play an important role in filament-based applications. However, polarization dependent clamping intensity inside filaments has been overlooked to interpret the polarization-related filamentation
K-shell X-ray emission from a Cu nanowire target irradiated by an ultraintense femtosecond laser pulse is studied using an elliptically bent quartz crystal and imaging plate. The designed bent crystal spectrometer has better spectral resolution, which is
