“…Tantalum and gadolinium targets were used in the x-ray source. Since the Kα emission lines bridge the gadolinium absorption edge but not the cerium one, different behaviours are seen in the two animals [36].…”

Ultrashort laser pulses are finding increasing applications in biology and medicine. Such pulses can be used directly or after non-linear modification. Direct utilization includes propagation studies in scattering media with applications in optical mammography, dosimetry for photodynamic therapy and species concentration assessment. Intense continua of electromagnetic radiation of very brief duration are formed in the interaction of focused ultrashort and intense laser pulses with matter. Two different kinds of experiment using such radiation are described, employing visible radiation and x-rays, respectively. Focusing into water leads to the generation of a light continuum through self-phase modulation. The propagation of the light through tissue was studied, addressing questions related to specific tissue chromophore absorption. When terawatt laser pulses are focused onto a solid target with high nuclear charge Z, intense x-ray radiation of few ps duration and with energies exceeding hundreds of keV is emitted. Biomedical applications of this radiation are described, including differential absorption and gated-viewing imaging.

“…X-ray spectromicroscopy is usually carried out using a continuously tuneable monochromatic beam generated by synchrotron sources suitable for research purposes. The use of laser-generated X-ray beams, with energies either side of particular K-edges, has also been investigated for this purpose [9].…”

“…X-ray spectromicroscopy is generally carried out using a continuously tuneable monochromatic beam generated by synchrotron sources, which is suitable for research purposes, as are the other techniques mentioned above. The use of laser generated X-ray beams with energies either side of a specific elemental X-ray absorption line has also been investigated for this purpose [10].…”
