Opto-acoustic response of an oscillating gas bubble.

(A) Theoretical response of a 100-nm-radius air bubble in water (blue solid curve) to the applied acoustic pressure (red dashed curve). (B) The acoustic response of the bubble becomes imprinted onto the intensity of light that illuminates the bubble. Here, the bubble is located in and the light is transmitted through a 300-nm-wide circular, water-filled hole in a 400-nm-thick silver film. Reprinted with permission from [136].
