Abstract: A verification information creation apparatus acquires an installation directory of software from equipment on which the software is installed, and acquires a file path and a hash value of a file whose hash value is acquirable based on types of files stored in the acquired directory. Then, the verification information creation apparatus creates verification information about the software, where the verification information includes the acquired file path and the hash value of the file.

Abstract: A laser apparatus for generating laser beams of predetermined wavelengths comprises a solid-state laser medium for generating a light beam having predetermined at least three fundamental wavelengths, at least three wavelength converters which respectively convert the light beam into harmonics corresponding to three primary colors of blue, green, and red, the wavelength-converter being circumferentially arranged, wavelength-converter holder for holding the wavelength converters, light blocking portions disposed between the wave length converters; rotating unit for rotating the wavelength-converter holder, thereby repeatedly positioning each of the wavelength converters and each of the light blocking portions on an optical axis of the solid-state laser medium, and a laser resonant optical system which resonates the light beams generated by the solid-state laser medium and outputs the harmonics converted by the wavelength converters.
