Abstract
A focus controlling component is configured to control a focus of a laser beam that passes through water and induces plasmas that emit signals. The focus of the laser beam is controlled such that the signals emitted by the induced plasmas interfere to form a combined signal that propagates in a desired direction.
Claims20
A device, comprising:
- a focus controlling component configured to control a focus of a laser beam that passes through water and induces plasmas that emit signals, wherein the focus of the laser beam is controlled such that the signals emitted by the induced plasmas interfere to form a combined signal that propagates in a desired direction.
A system, comprising:
- a laser source configured to generate and output a laser beam;
- and
- a focus controlling component configured to control a focus of the laser beam to have a three dimensional focal pattern with multiple foci, such that as the laser beams passes through water, plasmas are induced that emit signals that interfere to form a combined signal that propagates in a desired direction.
A method, comprising:
- generating a laser beam;
- controlling a focus of the laser beam to have a three dimensional focal pattern with multiple foci;
- and
- passing the laser beam through water to induce plasmas that emit sonar signals, wherein the sonar signals interfere to form a combined sonar signal that propagates in a desired direction.
