Presented here are observations that demonstrate how the deformation of millimetric cavitation bubbles by a uniform pressure gradient quenches single-collapse luminescence. Our innovative measurement system captures a broad luminescence spectrum (wavelength range, 300-900 nm) from the individual collapses of laser-induced bubbles in water. By varying the bubble size, driving pressure, and perceived gravity level aboard parabolic flights, we probed the limit from aspherical to highly spherical… 
Detailed experiments on weakly deformed cavitation bubbles
We present high-precision experiments conducted with the aim to better characterise weak deformations of single cavitation bubbles. Using two needle hydrophones and a high-speed photodetector, we
Temperatures produced by inertially collapsing bubbles near rigid surfaces
The dynamics of bubbles inertially collapsing in water near solid objects have been the subject of numerous studies in the context of cavitation erosion. While non-spherical bubble collapse,
Rebounds of deformed cavitation bubbles
Presented here are experiments clarifying how the deformation of cavitation bubbles affects their rebound. Rebound bubbles carry the remaining energy of a bubble following its initial collapse, which
What We Learned from Cavitation Bubbles in Microgravity
The present chapter is about the Flash and Splash project, which is dedicated to the study of bubble dynamics in microgravity. The story of this project started in 2004 with a simple curiosity on how
Study of sterilization effects on marineVibriosp. using interaction of cavitation with shock wave in a narrow water chamber
Cavitation bubbles could also be called as inertial bubbles because of their oscillation due to the pressure difference between inside and outside. After the passage of an underwater shock wave, the

Properties of luminescence from laser-created bubbles in pressurized water.
The properties of the luminescence pulse from collapsing laser-created bubbles in pressurized water are studied, and the duration of the light pulse is found to be linear in the maximum bubble size, but for a given bubble size it increases with the applied pressure.
Sonoluminescence temperatures during multi-bubble cavitation
Acoustic cavitation—the formation and implosive collapse of bubbles—occurs when a liquid is exposed to intense sound. Cavitation can produce white noise, sonochemical reactions, erosion of hard
Luminescence from spherically and aspherically collapsing laser‐induced bubbles
Luminescence from laser‐induced cavitation bubbles (SCBL) is investigated experimentally. This experimental technique offers several advantages over the acoustical driving technique for luminescence
Luminescence spectra of laser-induced cavitation bubbles near rigid boundaries.
It is found that the luminescence spectra of bubbles collapsing near a single boundary consist only of a blackbody continuum, which contains O H- emission bands similar to those found in multibubble sonoluminescence.
Luminescence from hydrodynamic cavitation
The majority of the research on cavitation luminescence has focused on the sonoluminescence or chemiluminescence generated by cavitation induced through ultrasound, with a lesser body of work on the
Probing luminescence from nonspherical bubble collapse
The luminescence from single laser produced cavitation bubbles for varying degrees of asphericity is investigated temporally, spatially, and spectrally. The degree of asphericity is controlled with
Shock waves from non-spherical cavitation bubbles
We present detailed observations of the shock waves emitted at the collapse of single cavitation bubbles using simultaneous time-resolved shadowgraphy and hydrophone pressure measurements. The
Single-bubble sonoluminescence
Experimental and theoretical efforts to understand single-bubble sonoluminescence, which occurs when an acoustically trapped and periodically driven gas bubble collapses so strongly that the energy focusing at collapse leads to light emission, are reviewed.
The quest for the most spherical bubble: experimental setup and data overview
We describe a recently realized experiment producing the most spherical cavitation bubbles today. The bubbles grow inside a liquid from a point plasma generated by a nanosecond laser pulse. Unlike in
Acoustic transient generation by laser‐produced cavitation bubbles near solid boundaries
The acoustic transients emitted after breakdown and cavitation bubble collapse upon focusing a Q‐switch laser pulse into a liquid are investigated with special emphasis on their modifications induced
