    摘要: A compact, lightweight, laser target designator uses a TIR bounce geometry to place an end-pumped gain element functionally in the center of the resonator path, thereby allowing the resonator path to be terminated by a pair of crossed Porro prisms, so that the designator produces a high quality beam that is insensitive to alignment and temperature, and is low in manufacturing cost. Some embodiments fold the Porro legs of the resonator path back toward the gain element for compactness. Embodiments use a single gain element as both an oscillator gain element with TIR and as an output amplifier gain element without TIR. Various embodiments use block optical elements in a planar layout on a standard support medium such as aluminum to facilitate automated manufacturing.

    摘要: Techniques are disclosed for fabricating optical instrumentation. The techniques can be used, for instance, to populate an optical bench with several optics that can be simultaneously bonded and simultaneously verified to precise assembly, and without the use of adjustable mounts or active alignment. The techniques may be embodied, for instance, in a jig designed for operatively coupling to a given optical bench. The jig includes cut-outs that identify placement locations for the various optical components on the underlying optical bench. Thus, once the jig is secured to the optical bench, precise placement of the optical components is simplified. In some such embodiments, the jig further includes a clamping assembly for each cut-out, so that once an optical component is placed on the optical bench via that cutout, the clamping assembly can be engaged to hold that optical component in place while a deposited bonding agent is cured.

    摘要: A terahertz imaging system and method of use including a compact Yb-doped fiber laser-pumped ZGP crystal as a THz source and an uncooled microbolometer array as a detector. According to the present invention, semiconductor lasers are also drive current modulated to produce desired laser pulsewidth, repetition rate and wavelengths needed for DFG THz generation in various non-linear crystals. The fiber-coupled semiconductor lasers provide at least two wavelengths that will produce THz radiation by DFG in non-linear converter. These two wavelengths are combined and amplified in a single Yb fiber amplifier chain. Yb amplifier is staged in continually increasing core diameters to provide significant signal amplification while suppressing deleterious non-linear effects.

    摘要: A monolithic pumped laser cavity design is disclosed. Elements of the laser cavity, such as gain material, Q-switch, reflector, and outcoupler, are contact bonded together with a thermally conductive epoxy. The assembly is then operatively coupled to a heat sink (e.g., by mechanical or chemical means). The assembly is potted in thermally conductive potting material. The stacked elements or a subset thereof may be bonded to heat sink mounts and/or face cooling layers. In this fashion, various elements can be easily assembled and bonded together to provide the desired combination of laser energy, pulse width, and repetition frequency. The thermally conductive potting material provides structural integrity, as well as thermal management by extracting heat from the encased assembly to the heat sink. The optional heat sink mounts and face cooling operate to further extract heat and reduce thermal loading. Outcoupling to fiber may also be provided.

    摘要: A laser amplification system is disclosed that enables reliable operation over large ambient temperature operating window, as well as a significant reduction of laser temperature sensitivity typically associated with diode pumped lasers. The techniques employed by the system effectively eliminate damaging gain hot spots and lower ASE and ESA thresholds, thereby increasing laser peak and average power levels. Additionally, the techniques allow for thermal programming of active gain medium material to minimize thermally induced aberrations. In one particular example embodiment, a variable dopant concentration multi-pass laser amplifier is provided having a customized active ion concentration profile, tailoring the combination of laser absorption and gain distribution using a ceramic YAG host.
