Energy Scaling of Quasi-Monoenergetic Ions Accelrated by Laser Radiation Pressure

What is it about?

Generation of quasi-monoenergetic ions is achievable by laser radiation pressure acceleration. However, in 2D or 3D geometry, due to Rayleigh-Taylor instability, the acceleration time and energy are largely limited. We studied the final obtainable ion energies with different input amplitudes and presented a scaling on it. We also provided an interpretation on the dependence of the acceleration times to these different laser amplitudes.

Why is it important?

- A scaling to estimate the achievable energy of quasi-monoenergetic ions by laser radiation pressure acceleration. - An explanation on the dependence of the Rayleigh-Taylor instability induced transparency time to different laser amplitudes.
