TL;DR: In this paper, a novel scheme is analyzed for efficient generation of vacuum ultraviolet radiation through four-wave mixing processes assisted by the Stark chirp of two photon resonance, including those leading to Stark-chirped rapid adiabatic passage.

TL;DR: In this article, the authors present results on the recording of holographic spectral filters in the DuPont 50 micrometers thick holographic photopolymer film from DuPont, which is a good candidate to fill in the gap and obtain filters with the desired selectivity.
Abstract: Holographic spectral filters become popular nowadays in various kinds of wavelength selective devices. The attractive feature of holograms is the possibility to widely vary the final parameters of a filter by choosing the appropriate recording material and recording geometry. However, up to a recent time there was a kind of a gap in attainable spectral selectivity due to the thickness of available materials. The ordinary materials, such as DCG, photopolymers, silver halide etc. are usually 20-30 micrometers thick. The very thick materials, namely porous glasses, PDA and some others start from the thickness of a few hundreds of micrometers. And because of that it was rather difficult to achieve the spectral selectivity of the order form several nanometers up to 20-30 nanometers, which are magnitudes required for many applications. The new holographic photopolymer film from DuPont, 50 micrometers thick, is a good candidate to fill in the gap and to obtain filters with the desired selectivity. This paper presents results on the recording of holographic spectral filters in this material.
