(54) Title: METHOD FOR CREATING, TRAPPING AND MANIPULATING A GAS BUBBLE IN LIQUID
(57) Abstract: A method for producing,
trapping and manipulating a gas mi-
crobubble in liquid is disclosed. The
method includes providing a pulsed
laser source for generating a pulsed laser
radiation and focusing optics; and focus¬
ing a pulsed laser radiation to a focal
zone within the liquid, with energy ex¬
ceeding the threshold of optical break¬
down in the liquid at the focal zone. It is
also suggested to use focusing optics to
focus the laser beam to a focal point at a
depth close to the compensation depth
of the focusing optics for spherical aber¬
ration.
