Laser excitation ultrasound in light absorbing liquids imputing laser radiation through optical fiber with colloidal coating of distal tip by a single layer of transparent spheres
Author(s): Bredikhin Vladimir
Efficient converters of optical laser radiation into high frequency acoustic for medicine and technologies are an important applied problem. A possible solution is to inject radiation into a liquid through the fiber, the distal end of which is covered by a layer of transparent microspheres. Microspheres act as lens here creating highly concentrated areas of light radiation in the liquid. In the presence of light absorption in the liquid, there arises a system of local heated volumes which leads to an optoacoustic (OA) response due to the thermoelastic effect. From this point of view, the layer of transparent microspheres at the distal tip of the fiber in a light absorbing medium can be considered to be a fiber laser–acoustic converter (LAC). Two opposite schemes of LAC are i... view more»
