Enhanced laser-driven proton acceleration via improved fast electron heating in a controlled pre-plasma

Scientific Reports, 2021
The interaction of ultraintense laser pulses with solids is largely affected by the plasma gradient at the vacuum–solid interface, which modifies the absorption and ultimately, controls the energy distribution function of heated electrons.

Laser irradiation to produce amorphous pharmaceuticals [PDF]

International Journal of Pharmaceutics, 2016
Using a high-power CO2 laser to irradiate powder beds, it was possible to induce phase transformation to the amorphous state. Irradiation of a model drug, indometacin, resulted in formation of a glass. Varying the settings of the laser (power and raster speed) was shown to change the physicochemical properties of the glasses produced and all irradiated
