摘要： The present invention is directed to a chirped dichroic mirror comprising a stack of alternating high refractive index and low refractive index layers, a front end portion including an antireflective coating followed by an impedance matching region in which the ratio of the optical thickness of a high refractive index layer to the optical thickness of the next following low refractive index layer is adiabatically increasing to a first value, the impedance matching region being followed by a chirped mirror region where the Bragg wavelength of the layer pair is generally increasing or generally decreasing, characterized in that the layers in a back end region form a second impedance matching region in which the ratio of the optical thickness of a high refractive index layer to the optical thickness of the next following low refractive index layer starts at the value of this ratio in the adjacent chirped mirror region and is then adiabatically decreasing in order to provide matched impedance to the surrounding medium over the transmission spectral band.

摘要： Disclosed is a method for producing a multilayer Laue lens. The object to provide a method for producing a wedged MLL that can be operated over a large range of wavelengths, and which preferably requires only a linear stage to adjust the positions of the lens as the wavelength is changed, is achieved by providing a lens blank comprising a substrate element having a flat upper surface extending in a plane defined by orthogonal axes x, y, z, wherein x and z extend in the plane and y extends normal to the plane, a layered structure deposited on the upper surface of the substrate element in such a way that at least two different materials are layered upon one another in an alternating manner, wherein the y-extension of the layered structure is constant along the x-axis and varies along the z-axis within a ramp section where the y-extension of the layered structure increases from a starting point, where first particles of material of the layered structure are deposited on the upper surface of the substrate element, to a saturation point, where a maximum y-extension of the layered structure is reached; and slicing a lens out of the lens blank by slicing through the ramp section in parallel to the y-axis but not parallel to the x- and z-axes.

The deposition source has a material outlet opening from which material is emitted. A longitudinal axis of an elongate central region of the material outlet opening extends parallel and centrally between the edges of the material outlet opening. The deposition source is mounted to the source mounting portion such that the longitudinal axis of the central region is parallel to the first axis. The shielding element has an aperture. The drive arrangement controls rotation of the source mounting portion, adjustment of a width of the aperture, and relative movement between the substrate holder and both the source mounting portion and the shielding element.

摘要： A method of producing a multilayer magnetoelectronic device and a related device. The method includes depositing a multilayer structure including at least two ferromagnetic layers disposed one on top of the other and each having a magnetic anisotropy with a corresponding magnetic moment. A magnetization curve is specified for the magnetoelectronic device. The number of ferromagnetic layers and, for each of the ferromagnetic layers, the magnetic moment and the magnetic hardness for obtaining the specified magnetization curve are determined. For each of the ferromagnetic layers a magnetic material, a thickness, an azimuthal angle and an angle of incidence are determined for obtaining the determined magnetic moment and magnetic hardness of the respective ferromagnetic layer. The multilayer structure is deposited using the determined material, thickness, azimuthal angle and angle of incidence for each of the ferromagnetic layers.

Furthermore, the invention relates to use of a self-contained optical assembly in a device (2) for characterizing an ultrashort laser pulse. The device (2) comprises an imaging optical element (4) configured to image the incident laser pulse (6) in a direction of a straight line (L). A first optical element (10) is configured to apply predetermined varying group delay dispersion on the line focused laser pulse. A non-linear optical element (14) is configured to generate a second harmonic laser pulse (30). An optical grating (20) generates a diffraction of the second harmonic laser pulse, which is imaged on a flat sensor (24).
