A first optical system irradiates a target with a detecting wave and making the detecting wave that is transmitted through the target incident upon the electrooptical crystal. A second optical system slants a pulse plane of a probe wave relative to a pulse plane of the detecting wave and making the probe wave incident upon the electrooptical crystal. A camera detects the probe wave passing through the electrooptical crystal. The first or second optical system includes a compensating component which partitions a beam cross section of the detecting wave or the probe wave into unit areas.

Electromagnetic wave imaging apparatus

A magnetic recording medium used for the thermally assisted magnetic recording system which fires a laser beam at a magnetic recording medium to partially heat the medium and applies a magnetic field from the outside to the part heated to lower the coercivity for recording. The magnetic recording medium is configured by a glass substrate on which a heat radiation layer, heat retention layer, intermediate layer, and recording layer are stacked. Further, the heat retention layer is configured by a member having an effective refractive index lower than the effective refractive index of the recording layer and having an temperature diffusion coefficient determined by the specific heat, density, and heat conductivity rate higher than glass and lower than metal. The material with a high temperature diffusion coefficient is used lowered in temperature diffusion coefficient using a porous structure or granular structure.

An object is to provide a photoelectric conversion element having a side surface with different taper angles by conducting etching of a photoelectric conversion layer step-by-step. A pin photodiode has a high response speed compared with a pn photodiode but has a disadvantage of large dark current. One cause of the dark current is considered to be conduction through an etching residue which is generated in etching and deposited on a side surface of the photoelectric conversion layer. Leakage current of the photoelectric conversion element is reduced by forming a structure in which a side surface has two different tapered shapes, which conventionally has a uniform surface, so that the photoelectric conversion layer has a side surface of a p-layer and a side surface of an n-layer, which are not in the same plane.
