Compact high-repetition-rate femtosecond laser-driven hard x-ray source

A compact, high-repetition rate, ultrashort-pulse laser-driven hard-x-ray source based on the combination of a femtosecond laser system with an x-ray diode is demonstrated. A comparison with available laser-plasma hard-x-ray sources is presented. Hard-x-ray fluxes exceeding 1010 photons/s (emitted in 4π) are realized at a repetition rate of 250 kHz. Numerical modeling is performed which proves that picosecond and sub-picosecond hard-x-ray pulses can be produced with this source.
