Abstract

The ultraviolet short-pulse laser light emitted from the ultraviolet short-pulse laser light source 1 is focused on and caused to irradiate a macromolecular crystal 8 contained in a sample container 6 via a shutter 2, intensity adjusting element 3, irradiation position control mechanism 4, and focusing optical system 5. The sample container 6 is carried on a stage 7, and can be moved in three dimensions along the directions of the x, y and z axes in an x-y-z orthogonal coordinate system with the direction of the optical axis being taken as the z axis; furthermore, the sample container 6 can be rotated about the z axis. Working of the macromolecular crystal is performed by means of ultraviolet short-pulse laser light that is focused on and caused to irradiate the surface of the macromolecular crystal 8. In this way, various types of working can be securely performed on macromolecular crystals with little damage and by means of a simple operation.
