摘要： Saturated tabletop lasers having increased output energy and operating at 5 Hz repetition rate, were demonstrated at wavelengths about 18.9 nm for a molybdenum target, 16.4 nm for a ruthenium target, 14.7 nm for a palladium target, 13.9 nm for a silver target, and 13.2 nm for a cadmium target in transitions of nickel-like ions. The results were obtained using a sequence of two, plasma-generating pre-pulses, each having sub-Joule energy followed after a selected delay period by picosecond laser plasma excitation pulse having an energy of about 1 J at angles of incidence optimized for maximum energy deposition.

摘要： A compact, high repetition rate, extreme ultraviolet/soft x-ray laser and method for generating such radiation are described. Excitation of the gaseous or vaporous lasing medium is achieved by discharging energy stored in a solid- dielectric capacitive device through a capillary channel containing the medium. By reducing the inductance of the discharge apparatus, excitation of the laser medium can be achieved without the use of Marx generators. Neon-like Ar atom laser pulses at 46.9 nm having energies of about 13 µJ are generated at repetition rates up to 12 Hz. Between 2 and 3 x 10 4 laser pulses can be generated using a single capillary. Such a source of intense, short-wavelength radiation can be used for applications which include surface characterization of materials, high resolution imaging and printing, photochemistry and photophysics, laser ablation, characterization of x-ray optics, and dense plasma diagnostics.
摘要翻译：描述了紧凑，高重复率，极紫外/软X射线激光器和用于产生这种辐射的方法。气体或气相激光介质的激发通过将储存在固体介电电容器件中的能量通过包含介质的毛细通道放电来实现。通过减小放电装置的电感，可以在不使用马克思发生器的情况下实现激光介质的激发。以高达12Hz的重复率产生具有约13μJ能量的46.9nm的氖样Ar原子激光脉冲。可以使用单个毛细管产生2至3×10 4个激光脉冲。这种强烈的短波长辐射源可用于包括材料的表面表征，高分辨率成像和印刷，光化学和光物理学，激光烧蚀，X射线光学表征和致密等离子体诊断的应用。

摘要： A method and system for reading a security seal having a far-field pattern are described. Periodic nano-structure is generated on the surface of a substrate having spacings of hundreds of nanometers, or smaller, are affixed/generated directly onto the product. A laser beam with wavelength longer than the periodic spacings directed onto at least a portion of the substrate surface at a chosen angle of incidence and selected azimuthal angle relative to a chosen direction produces a unique far-field pattern that may be imaged by a digital image detector disposed at a chosen distance from the illuminated region, compared with a stored reference, and validated. The nanoscale sub-wavelength patterns are printed using extreme ultraviolet light and read with readily available visible/ultraviolet light. The security seal contains pattern invisible to the eye and optical microscope. Brand protection at different stages of life-span of a product, from production to purchase is therefore available.
