    Abstract: Provided herein is a method for forming a periodic microstructure on a surface of zirconia-based ceramics, which are not easily mechanically workable, without causing thermal adverse effects. A zirconia-based ceramic having a surface periodic microstructure is also provided. A linearly or circularly polarized laser beam is irradiated to a zirconia-based ceramic surface, and periodic irregularities are formed in a spot of the laser beam. Stripe-pattern irregularities parallel to the direction of polarization can be formed in a spot of a laser beam by irradiating a linearly polarized ultrashort pulsed-laser beam to a zirconia-based ceramic surface. A mesh-like raised region and a dot-like recessed region can be periodically formed by irradiating a circularly polarized ultrashort pulsed-laser beam to a ceramic surface.

  • Patent number: 10767088
    Abstract: When conventional photo-reactive compounds are to be liquefied with the application of light, liquefaction thereof is time-consuming due to poor sensitivity to ultraviolet light. In the case of conventional photo-reactive compounds, disadvantageously, light does not penetrate through layers to be adhered to each other when such layers are thick. Thus, peeling is not sufficiently performed. Accordingly, it is an object of the present invention to overcome such drawbacks of conventional photo-reactive compounds and provide a photo-reactive adhesive agent exhibiting high sensitivity to light for fluidization and capable of easy peeling.
