Numerical modeling of polycrystalline transparent materials exhibiting strong supercontinuum
and high-harmonic generation is challenging due to the random nature of these media. This paper describes
modeling approaches suitable for realistic simulation of extreme nonlinear optics in such materials.
We investigated the nonlinear optical properties of single- and poly-crystalline optical materials using ultrashort mid-infrared laser pulses between 3 and 4 µm. We compared visible to mid-infrared spectra between the materials. Measured energy conversion into all-order harmonics in polycrystalline materials exceeded 30%.
We report on design and construction of a high nanosecond and picosecond contrast kHz dual chirp pulse amplification (DCPA) system with >15 mJ/pulse, pulse duration < 35 fs, for developing an efficient MeV ion acceleration and fast neutron source.
We investigate the atmospheric propagation of high power 10μm – picosecond laser pulses over multi-km distances in the atmosphere. We predict that 10μm atmospheric filaments have noteworthy advantages when compared their shorter wavelengths counterparts, which are expected to have important impact in future applications.
Traditional display protocols have limitations in terms of fixed refresh-rates, high bandwidth requirements, and control over the display of frames. This paper demonstrates the performance results of an alternative approach utilizing a packetized display protocol architecture incorporating dynamic refresh-rates, high-speed capabilities, to bridge performance gaps.
