| Abstract: | Influences of the transparent liquids' bulk modulus,dynamic-viscosity coefficient and the absorbed laser pulse energy in the breakdown region on the peak pressure,the sound energy and the dominant frequency of the laser induced expanding sound are analyzed.An experimental system is developed for producing and measuring laser induced expanding sound in three transparent liquids-distilled water,alcohol and glycerin.The parameters of laser induced expanding sound are calculated within certain ranges of bulk modulus (0.2～7.0 GPa),dynamic-viscosity coefficient (0.001～30.000 Pa·s) and absorbed laser pulse energy (10～400 mJ).The results of theoretical calculation and experiment is as follows:Firstly,the dominant frequency,the peak sound pressure and the sound energy increase as the bulk modulus increases.Secondly,the peak pressure and the sound energy decrease as the dynmic-viscosity coefficient increases.Thirdly,the peak sound pressure and the energy increase as the absorbed laser pulse energy increases.Fourthly,the dominant frequency changes little as the dynamic-viscosity coefficient and the absorbed laser pulse energy change. |
