Abstract

In this chapter, studies on interactions of intense laser fields with transparent materials such as glasses, polymer targets, and solutions are reviewed from the viewpoint of the high-energy photon emission of EUV, soft X-rays, and hard X-rays. Fundamentals of the mechanisms leading to high-energy photon emission are summarized on the basis of experimental results, like X-ray emission spectra. Experimental setups for laser-induced hard X-ray emission from solutions and solids are provided and the effects of air plasma formation and sample self-absorption of X-rays on X-ray generation are described. Photo-ionization processes of transparent materials and effects of the addition of electrolytes are also considered. The effects of multi-shot and double-pulse irradiation of laser pulses on X-ray emission from solid materials and solutions are explained. Finally, some possible applications using X-rays from transparent materials are suggested.
