Source Optimisation of Laser-Plasma Bremmstrahlung for Applications in Engineering Imaging
High Power Lasers produce an intense burst of
Bremmstrahlung radiation which has potential applications in broadband
x-ray radiography. Since the radiation produced is through the
interaction of accelerated electrons with the remaining laser target,
these bursts are extremely short – in the region of a few ps. As a
result, the laser-produced x-rays are capable of imaging complex
dynamic objects with zero motion blur.
