| 摘要 |
A device for laser-optical generation of mechanical waves for processing and/or examining a body includes a laser light source for generation of laser light and a modulator, on which a generated laser light falls and with which, from an incident laser light, a predetermined laser light intensity distribution can be generated on or in the body, in such a way that mechanical waves are excited on or in the body, with which the body is processed and/or with which, via detection of said waves, the body can be examined. According to certain aspects of the invention, the modulator is formed as a diffractive optical element wherein a height profile structure is formed on the surface of the diffractive optical element, with which the phase of the incident laser light is varied, thus generating a predetermined laser light intensity distribution.
