Controllable Ring Diffraction Patterns on Silicon Induced by Bubble-Scattered Femtosecond Laser Pulses in Liquid (JTh2A.1)

Presenter: Sergey Romashevskiy, Joint Institute for High Temperatures

We report on producing circular ripple patterns of controlled geometry on silicon in liquid using a pair of femtosecond laser pulses. Such patterns occur by diffraction of the second pulse by the bubble, generated near the surface by the first pulse.
