摘要： Systems and methods for adjusting optical path length of an optical path are provided. The systems and methods can be used to controllably adjust optical path length in an external cavity laser. A representative optical path having a first end and a second end comprises a first transparent refractive element located in the optical path between the first end and the second end. The transparent refractive element is adjustable to adjust the optical path length of the optical path without changing the physical distance between the first end and the second end. A representative method includes introducing a transparent refractive element into the optical path and adjusting the transparent refractive element to change the optical path length without changing the physical distance between the first end and the second end of the optical path.

摘要： Systems and methods for forming a seal between members of an assembly are disclosed. In one embodiment, a seal is formed between a first member and a second member by establishing within the members a bounded volume and creating within the bounded volume a pressure differential with respect to the ambient pressure outside the bounded volume. The pressure differential results in a uniformly applied clamping force to the members thereby creating a reliable seal. A sealing member (such as solder, epoxy, or other sealant) is positioned between the first and second members and the resulting assembly is mechanically positioned such that heat can then be applied to melt the solder. Concurrently, the pressure differential is created which allows the externally applied mechanical positioning to be relaxed while the members are being sealed together. This system and method can be used to create hermetic seals.

摘要： A servo head for magnetic tape is provided. The head includes a substantial planar head surface. The head includes a leading edge that is disposed adjacent to the head surface such that the tape contacts the leading edge before passing over the head surface. The leading edge includes a rounded portion so as to form an air bearing between the head surface and the tape. The leading edge can include an abrupt change in slope at the leading edge. Alternatively, the leading edge can include a smooth transition.

摘要： A head design that reduces wear at the leading and trailing edges where the tape contacts the head while minimizing any adverse effects on the performance of the head. In one embodiment of the invention, a localized layer of wear resistant material is formed on the leading edge where the tape contacts the head before passing over the head recording surface. In a second embodiment, the leading edge is formed as wear resistant material embedded in the head structure adjacent to the recording surface. And, in a third embodiment, the leading edge is formed as a wear resistant material strip affixed to the side of the head structure. For each embodiment, the wear resistant material may also be applied in the manner described to the trailing edge where the tape may also contact the head after passing over the recording surface.

摘要： Pre-aligned, kinematically mounted modules including processing lasers, beam trains, and individually calibrated control beams are quickly and easily replaced on subassembly bases with minimal in situ alignment, and can maintain working-spot position to micron tolerances over ambient temperature variations of ±10° C. Subassembly bases, with features for kinematically mating to a plurality of pre-aligned laser modules and to a platform base incorporated in the laser processing tool, enable multi-module subassemblies to be quickly replaced with spare subassemblies of the same type, or swapped for subassemblies of a different type. The mating features and reversible locks are designed to mitigate thermal effects that are often a dominant cause of alignment drift in processing lasers.

摘要： A laser ablation system is controlled by an autofocus subsystem particularly optimized for precision ablation of large workpieces, in an open factory environment where temperatures are not tightly controlled, where the workpieces may have high-spatial-frequency features that affect the focus condition of the working beam. The autofocus operates at a high bandwidth to support high process speed. The autofocus beam shares most of its optical path with the working beam, so its measurements account for thermal effects in the beam train as well as the workpiece. The autofocus beam measures target or adjacent areas just before, or during, ablation, so that temperature drifts do not have time to change the effective focus error. The autofocus spot is substantially the same size as the working spot, so its measurements account for workpiece features of the same spatial frequencies that affect the working beam.
摘要翻译：激光烧蚀系统由自动聚焦子系统控制，该自动对焦子系统在温度不受严格控制的开放工厂环境中特别优化用于大型工件的精密烧蚀，其中工件可能具有影响工作焦点状态的高空间频率特征光束。自动对焦以高带宽工作，以支持高处理速度。自动对焦光束与工作光束共享其大部分光路，因此其测量结果表明光束列和工件中的热效应。自动对焦光束在消融之前或期间测量目标或相邻区域，使得温度漂移没有时间改变有效聚焦误差。自动对焦点的大小与工作点大致相同，因此其测量结果影响到影响工作光束的相同空间频率的工件特征。
