Overview sketch of the laser-driven cavitation X-ray imaging experiments carried out at the MID station of the European XFEL. The 1064 nm pump laser pulses excite cavitation events in purified water inside the cuvette. The electron density profiles of the expanding bubbles are probed by X-ray holography with well defined and adjustable time delays of a few ns up to several µs; at lower time-resolution, optical microscopy images are recorded. Using a microphone, the bubble lifetime is measured. |
