Claim 18:
19. The laser system of claim 18, wherein in the laser bond inspection on a composite structure, the output pulsed laser beam is directed onto a surface of the composite structure to interrogate an integrity of at least one bonding interface of the defined surface area within the composite structure; wherein:
the composite structure is formed by bonding at least two different layers of materials having the at least one bonding interface formed there between,
the output pulsed laser beam exerts compressive stress waves upon impacting over a defined area size on the surface of the composite structure;
a response of reflected stress waves signature over the defined area size of the surface of the composite structure is measured; and
determine if a bonding defect occurs over the defined area size within the at least one bonding interface formed there between the at least two different layers of materials, according to the response of reflected stress waves signature.
