Successful generation and application of optical few-cycle pulse and coherent x-ray pulse generation are one of the most prominent examples at the heart of strong-field phenomena, for which vacuum conditions and/or separate pressure-controlled gas media are generally required. Since, in practices, the traditional solid window materials used for x-ray beamlines may introduce undesirable high attenuation, or are subject to failure under high heat loads, as well as the laser pulse of few-cycle duration is frequency broadened and distortions, which are hardly to compensate for due to the (higher-order) dispersion when ultrafast driving laser and extreme ultraviolet (xuv) emission through from vacuum to atmosphere and vice verse. Plasma windows, a original concept developed by Ady Hershcovitch from Brookhaven National Laboratory for non-vacuum electron welding applications, show promise as an alternative to traditional window for the separation of the experimental vacuum environment from the pressure-controlled gas media for the optical few-cycle pulse as well as coherent x-ray pulse generation. With the typical properties of the plasma window, we will demonstrate the efficient and well-controlled generation of the intense few-cycle laser pulses from a self-compressed filament in gases with more energy throughput, and to drive high harmonic generation with such pulses in the same long interaction cell, as well as in the generation of isolated attosecond pulses from the intensity spike coupled out of the filament.
