摘 要: | 提出了一种光声效应的反冲压力模型,为了证实这种模型的合理性,讨论了光声信号的大小随激光功率密度的变化关系,得出了随激光功率密度的增大,光声信号会出现一个极大值和一个极小值。

The Recoil Pressure Model of Photoacoustic Effect in Solid |
| |
Abstract: | A recoil pressure model of the photoacoustic effect in solid is developed. The relation between the photoacoutic signal and the laser power density is studied to test the model. There are a maximum and a minimum of the photoacoustic signals with the increase of the laser power density. |

Keywords: | photoacoustic effect in solid pulse laser plasma |
