We report on dynamical observations of femtosecond-laser-generated bubbles in water using a single-laser-source pump/probe setup combined with stroboscopic imaging. With this simple setup, we accurately measure the transmission of a probe beam and simultaneously record images giving the size and lifetime of single-pulse-generated bubbles. Our experiments indicate that stable bubble nucleation can be obtained with pulses repetition rate up to 142 kHz, which offers promising perspectives for high-throughput jetting.  (Download / PDF)
