    • The invention relates to a method and an apparatus for producing a hologram in an optical medium, especially for storing data in said optical medium. In said method, the hologram is generated in the optical medium by means of laser beams which are formed from a laser beam emitted by a free-running semiconductor laser, are irradiated onto the optical medium, and optionally extend in opposite directions while extending in such a way as to spatially overlap at least in part in the optical medium. In order to produce highly contrasting holograms by using inexpensive components, the reflective unit (15) is arranged such that the optical path (?x) between the focus of the laser beam in the storage medium (10) and the reflective surface of the reflective unit (15) in the area of the optical axis meets the following condition: ?x = 0.5 * ?s * a, wherein a is a natural number that is greater than or equal to 1, and ?s represents a distance between adjacent coherence centers of the laser beam generated by the semiconductor laser (16).

    • The invention relates to a method for producing a bone cement with bioactivity and a corresponding bone cement kit. The method comprises mixing a monomer-free polymethylmethacrylate (PMMA) with a mass average molecular weight of 30,000 to 200,000 and an acid number of 10 to 350 mg KOH per g polymer in am amount of 5 to 13 wt. %, with a solvent for PMMA and 40 to 97 wt. % of at least one crystalline and/or glass-crystalline material is added to the mixture with the proviso that the crystalline or glass crystalline material contains 15 - 60 wt.% CaO, 30 - 50 wt.% P2O5, 0 - 9 wt.% ZrO2 and 0 - 3 wt.% fluoride and the mixing and stirring is carried out at a temperature of 10 to 500°C to give a free-flowing mixture with an open processing time in the range 1 to 20 minutes. The addition id preferably of 0.1-10 wt.% ZnO. The material is preferably used as cement or bone filler material in dentistry and as cement for kyphoplasty or vertebroplasty and as fixing cement for joint prostheses.
