An apparatus for inducing cavitation at a surface of a specimen includes a cavitation chamber, a window extending through the wall of the chamber to an area outside the chamber, a test specimen positioned within the chamber, and a cavitation media inside the chamber and in contact with the surface of the specimen. A laser light source is disposed outside the chamber, and is operable to provide a laser beam through the window and into the cavitation media. The laser light source generates a shock wave in the cavitation media, the shock wave causing cavitation at the surface of the specimen.
