Characteristics Research on Cross-Media Interaction and Transmission of Ultrashort Pulse Laser

The characteristics on cross-media (from air to water) interaction and transmission of ultrashort pulse laser are studied numerically and experimentally. After the analysis on the theories and measurement results of the laser induced sound by breakdown mechanism, influencing factors on atmospheric transmission of laser and plasma effect of ultrashort pulse laser transmission in the atmosphere are studied as well as the effect of sound transmission under water.
