INVESTIGATION ON THE INTERACTIONS AMONG LIGHT, MATERIAL AND TEMPERATURE FIELD IN TRANSIENT LENS EFFECT

摘要

Recently, analysis and diagnosis based on laser technology is progressing rapidly by means of the advancement of the technology related to optics. It is remarkable that the technology using high intensisty laser pulses, e.g. nanosecond to femtosecond laser pulses, has advanced. Using intense laser pulses gives high industrial advantages. However, there are few reports to investigate the relation between laser pulses and liquid. In this research, we investigate the influence of the local temperature distribution generated in applications that utilized cw-laser. Furthermore, we discussed the transient lens effect that is based on the interaction between light, material and temperature field experimentally and theoretically.
