| Outline of Final Research Achievements |
In this research project, we obtained pressure waves by focusing femto-seconds pulse laser with establishment of optical system. The maximum pressure at optical focal point was obtained, and it was estimated to be 0.2-0.3 MPa by averaging every maximum pressure with shot number, as the signal noise ratio (S/N ratio) of each shot by pressure sensor was not good. This value is considered to be enough for stimulating cells, but small for disintegration of cells. From this result, it was suggested that these shock waves induced by short time pulse laser can be applied to regenerative system. In addition to this, it was found that micro bubbles can be generated with plasma luminescence. This finding should be investigated in future.
