    Abstract: A coolable slab laser is disclosed wherein the effects of thermal gradients within the laser element are minimized. The laser beam is made to traverse the longitudinal axis of the laser element a plurality of times in a zig-zag fashion so as to travel parallel to the thermal gradient as closely as possible. The laser element itself is an eight sided solid with beam entrance and exit areas on the same end of the element.

    Abstract: A low-cost waveguide taper for interconnecting two circular waveguides which differ substantially in size is constructed from a plurality of reinforced, thin-walled conical sections having predetermined taper angles and axial lengths to minimize the effects of spurious modes generated at the junctions of the conical sections.

    Abstract: A low-cost waveguide taper for interconnecting two circular waveguides which differ substantially in size is constructed from a plurality of reinforced, thin-walled conical sections having predetermined taper angles and axial lengths to minimize the effects of spurious modes generated at the junctions of the conical sections. For the particular example of a waveguide taper interconnecting a circular waveguide of 2.25 inch diameter to an oversize circular waveguide of 29.7 inch diameter and suitable for the propagation of the TE*01 mode at X-band frequency, the taper comprises 12 conical sections having four different taper angles. The three cone-cone junctions and the cone oversize waveguide junction form two pairs of mode converting junctions which are interlaced such that the first and third and also the second and fourth junction effects each cancel as a pair and this interlaced concept permits fabrication of the particular waveguide taper having a minimum length of 17.5 feet. The larger diameter conical sections of the taper are fabricated by forming longitudinal welds along the seams formed by rolling thin aluminum sheet metal into the desired conical shapes. The sections are then precisely aligned and connected together by means of flanges epoxied on the sections.

    Abstract translation: 用于互连尺寸基本不同的两个圆形波导的低成本波导锥形由具有预定锥角和轴向长度的多个加强的薄壁锥形部分构成，以最小化在圆锥形的接合处产生的杂散模的影响 部分。 对于将直径为2.25英寸的圆形波导与29.7英寸直径的超大圆形波导相互连接的波导锥形的特定示例，适合于在X频带频率下传播TE DEG 01模式，锥形包括12个具有四个 不同的锥角。 三个锥锥结和锥形超大波导结形成两对模式转换结，其交织使得第一和第三以及第二和第四连接效应各自取消成对，并且这种交错概念允许制造特定的 波导锥度最小长度为17.5英尺。 锥形的较大直径的锥形部分通过沿着通过将薄铝板金属轧制成所需圆锥形状而形成的接缝而形成纵向焊缝。 然后这些部分通过在部分上环氧化的凸缘精确对准并连接在一起。
