Efficiency-optimized relativistic plasma harmonics for extreme fields
Experimental details The experimental results presented in this paper were obtained using the Gemini laser system. A DPM…
19.2-attosecond X-ray pulse lets scientists freeze electron motion
Electrons just got caught in the act. For decades, scientists have known that electrons quietly dictate almost everything,…
Transient domain boundary drives ultrafast magnetisation reversal
Time-resolved magnetic soft-X-ray spectroscopy We investigate a typical nanometre-scale heterostructure consisting of an amorphous ferrimagnetic Gd25Co75 alloy with…
Noncollinear harmonic spectroscopy reveals crossover of strong-field effects
Figure 1a illustrates the generation of ultrahigh order wave-mixing photons resulting from the superposition of an intense fundamental field…
