The opto-acoustic generator of ultrasound waves comprises an optical fiber associated to a laser-energy source, and an opto-acoustic transducer which is applied to said fiber and is designed to be impinged upon by the laser beam and to absorb partially the energy, converting it into thermal energy, thus bringing about the formation of ultrasound waves by the thermo-acoustic effect. Said opto-acoustic transducer consists of a layer or film containing prevalently graphite, which is applied on a surface of said optical fiber.

Abstract
The opto-acoustic generator of ultrasound waves comprises an optical fiber associated to a laser-energy source, and an opto-acoustic transducer which is applied to said fiber and is designed to be impinged upon by the laser beam and to absorb partially the energy, converting it into thermal energy, thus bringing about the formation of ultrasound waves by the thermo-acoustic effect. Said opto-acoustic transducer consists of a layer or film containing prevalently graphite, which is applied on a surface of said optical fiber.
