摘要: We experimentally investigated the oscillation of water vapor microbubble generated in degassed using thermoplasmonic effect. A CW laser was focused on a gold nanoisland film to realize localized heating and subsequent generation microbubble. The bubble found be oscillating at 0.5{1 MHz although power constant. When spot size, namely, fixed 2.7 μm, diameter frequency almost independent power. On other hand, size significantly increased as increases from 2.8 3.7 μm. Besides, decreased increased, which same order magnitude resonance frequency. These results suggest that behavior is highly dependent outmost region spot, contacts periodically.
