Crystalline High Aspect Ratio Nano-Pillars Generated by Ultrafast Bessel Beam from Sapphire
Ultrafast lasers deliver high energy density through laser-matter interaction generating extreme pressures and temperatures. The energy deposited in the bulk of transparent materials can lead to the amorphization or re-crystallization of the modified matter [1]. The extreme conditions can even allow the observation of previously unreachable crystalline structures [2].
