摘要： The various laser architectures described herein provide increased gain of optical energy as well as compensation of optical phase distortions in a thin disk gain medium. An optical amplifier presented herein provides for scalable high energy extraction and gains based on a number of passes of the signal beam through a gain medium. Multiple, spatially separate, optical paths may also be passed through the same gain region to provide gain clearing by splitting off a small percentage of an output pulse and sending it back through the amplifier along a slightly different path. By clearing out the residual gain, uniform signal amplitudes can be obtained.

摘要： Optical filaments are formed controllably in a gaseous medium such as air. A phase plate introducing a phase discontinuity or other localized optical inhomogeneity is introduced into the path of the pulsed high-power laser beam that forms the optical filaments in the medium. The locations and characteristics of the phase discontinuities or singularities are selected to control the number and locations of the optical filaments.

摘要： A laser amplifier system is presented including a pump regenerative amplifier. The amplifier generally has a cavity defined by a pair of end cavity mirrors between which an amplified pump pulse oscillates. The amplifier also includes an interaction cell with a tunable gain medium amplifies laser pulses (e.g., Raman gain). The interaction cell may be positioned within the pump amplifier cavity and an input pulse may be injected into the cavity of the amplifier to transit through the tunable gain medium of the interaction cell. A pump pulse transfers energy via interaction with the input pulse (e.g., Raman interaction) as the pulses counter-propagate through the gain medium of the interaction cell. Amplification of output laser pulses, however, is generally achieved according to the wavelength of the pump laser pulses thereby providing a wavelength dependent, or “tunable”, means for amplifying laser pulses.

摘要： Systems and methods presented herein are generally directed to enhancing electrical discharge. A hollow conical electrode may be provided to discharge electrical energy in a directed manner. The conical electrode has two openings: a larger entrance opening; and a smaller exit opening. These openings are configured to allow radiated energy to pass therethrough and form a preferential path of electrical conduction. The larger entrance opening has a surface with a radius of curvature that is larger than that of the second smaller exit opening. The smaller exit opening directs electrical energy to the path because of stronger electric fields. In one embodiment, a protruding electrode element is configured with the smaller exit opening to further enhance electrical discharge by focusing electric fields in the vicinity of the protruding electrode.

摘要： Systems and methods are presented herein that provide for ignition of explosive devices through electric and/or electromagnetic discharge. In one embodiment, an electrostatic discharge is directionally propagated through air to conduct electric current to the explosive device. The electric current may ignite the explosive device via heat, via triggering of ignition circuitry, via induced electric current conduction to the explosive material therein and/or via direct electric conduction to the explosive material therein. Alternatively, or in addition to, electromagnetic energy may be directionally propagated to the device through a waveguide. Such electromagnetic energy may be in the microwave region and may heat and/or induce electric current in the explosive device. In either instance, the directionally propagated energy may be time varying. In one embodiment, a system is configured with a vehicle to distally position the directionally propagated energy to the explosive device such that damage caused by the device is inhibited.
