High harmonic generation (HHG) from gaseous targets has been demonstrated to be an attractive method to generate ultra-short coherent radiation in the extreme ultraviolet spectral range and attosecond pulses. Over the last decade, laser-induced plasma plumes (LIPs) produced from solid surfaces have been recognized as alternative media for HHG. It has been found that the generation efficiencies and cut-off photon energies vary significantly among different target species, and interesting
In recent years, the study of in-plane anisotropic optoelectronic thin film materials has attracted a great deal of attention in the field of polarized optoelectronic applications due to their ability to be integrated and miniaturized. The existing anisotropic two-dimensional materials are limited in variety and mostly mechanically exfoliated, making it difficult to achieve large-area material preparation, which greatly limits their application in practical applications. Therefore, it is necessary to explore an artificial anisotropic thin film material with excellen

A popular media for high-order harmonic generation (HHG), nanoparticles are combine the low average density of gases and local high density of solids, which could be beneficial for harmonic conversion efficiency. Until now, the best way to form nanoparticles with low spatial density distribution is in the way of laser ablation plume from prefabricated nanoparticles.
The core parts for optical data processing are all-optical logic gates, which are projected to play a critical role in future ultrafast high-capacity communications networks. However, while these logic functions are handled by highly limited and high-cost single-function logic operations, the necessity for high capacity and low-cost signal processing became imperative.
The recombination loss of perovskite polycrystalline film in grains and grains boundary has not been optimized, which makes it face the bottleneck. Monocrystal perovskite solar cells based on non-grain-boundary films have recently become candidate materials to further push perovskite solar cells to their theoretical limits. However, due to the imbalance between absorption length and carrier diffusion length, the fabrication of monocrystal for high-efficiency perovskite solar cells has been unsatisfactory. The thickness of monocrystal is usually too large, resulting in poor efficiency of charge carrier collection.
