%X The complete evolution of holmium-laser-pulse-induced cavitation bubble movements and acoustic transients underwater are investigated experimentally. The laser was single fiber-guided and had a 300 mJ pulse energy and 300 ¦Ìs pulse duration (full width at half-maximum). In our experiments, more than four oscillations and four acoustic transients were demonstrated. 272 ¦Ìs after laser onset, the cavitation bubbles reached their maximum transverse and longitudinal lengths of 2046 and 1914 ¦Ìm, respectively. The maximum transverse and longitudinal bubble wall velocities were 28.9 and 39.2 m/s at 560 and 528 ¦Ìs after laser onset, respectively. This investigation will be helpful to make good use of cavitation effect in medical applications of holmium laser pulses.
