X-Ray Generation
X-ray generation using ultrashort high-energy laser pulses is an attractive technique for industry, medicine, and material science. In particular, the generated X-rays can be applied in X-ray spectroscopy and diffraction measurements.
The use of femtosecond pulses enables the generation of X-rays with femtosecond temporal and angstrom-scale spatial resolution, allowing direct observation of atom-level structural changes in different samples. The properties of X-rays generated by femtosecond laser pulses are comparable to that of synchrotrons, but laser systems are significantly simpler and more compact than synchrotrons.
The brightness of generated X-rays scales linearly with the laser repetition rate. The brightness and conversion efficiency of X-rays using high-repetition-rate and high-average-power PHAROS femtosecond lasers are comparable to those achieved using multi-millijoule pulsed laser sources. This suggests that femtosecond laser systems such as PHAROS and CARBIDE are the solutions in the quest for tabletop X-ray sources.
