Outline of Final Research Achievements	Modification of surface quality and property, which is rough or smooth, stress relieving or adding, cleaning, for precision, micro and complex parts is assumed to do, laser induced micro shockwave under-solution generator device which is shockwave under-solution was generated by thermal expansion of thin metal film coated on optical fiber end was constructing of the basis of laser induced shockwave underwater technic. The device was generated shockwaves about 3.3MPa in pressure and it's depend on quality of optical fiber end and metal thin film coated on the end.
