Abstract

Thesimilitudewasanalyzedbetweenthecharacteristicsofexplosionbubblesgeneratedby laser-inducedbreakdownanddetonatorexplosioninwater.Bycombiningahighpowerlaser,anopticalfocussystem, ahigh-speedcameraandahydrophone,ameasurementsystemwasdevelopedtoexperimentallyinvestigatethelaser- inducedbreakdowninliquidssuchaswater,alcohol,siliconinthe casesofthedifferentlaserenergy.Basedonthedevelopedmeasurementsystem,aseriesoflaser-inducedbubblecharacteristicswereobtained, whichincludedtheimagelistsofexplosionbubbledynamics, expansionandcollapse,andtheparametersofexplosionbubblediameterevolvements,bubbleexpansionandcollapseshockwavevelocitiesandacousticsignalintensities.
