An Integrated Resonantly-Coupled Dual-Wavelength Tunable External Cavity Laser is achieved using a common resonator and two or more independent resonators to select the two laser wavelengths. The resonators are present within the laser’s cavity, so no external frequency offset locking is required. The lasers are intrinsically frequency offset locked through the common resonator. The architecture achieves frequency offset locking by monitoring and controlling low-speed signals, greatly reducing the cost, size, weight, and power of comparable locking approaches. The laser provides broadband locking, because locking is achieved in the optical domain, without the need for high-frequency electronics.

An electrical conduit comprising a shell body and a transmission core positioned between a first end portion and a second end portion within the shell body and a tunnel cavity extending through the shell body. The transmission core is suspended within the tunnel cavity and spaced from the shell body and the first electrical connector and the second electrical connector are in communication with the transmission core.
A method of additively manufacturing a part by printing the part, layer-by-layer, on a substrate, such that the part is formed of a plurality of layers, each of the layers is built up by simultaneously: (i) directing a fiber feedstock stream, of fiber feedstock, toward a point of deposition on the substrate or a previously deposited layer; (ii) directing one or more precursor streams, of one or more precursors, toward the point of deposition on or near the fiber feedstock stream; and (iii) directing one or more energy sources toward the point of deposition; the one or more precursors reacts to form a ceramic that is deposited on and around the fiber feedstock, thereby forming a ceramic matrix composite that includes the ceramic formed from the one or more precursor streams embedded with fiber from the fiber feedstock; and repeating steps (i) to (iii) until printing the layers is complete.
An electronics cooling system including an electronics magazine. The electronics magazine includes a magazine body, one or more capsule sockets, one or more interface shorings positioned within the magazine body relative to the one or more capsule sockets and a magazine heat conductive interface positioned within the magazine body relative to at least one of the one or more capsule sockets. The cooling system includes one or more electronics capsules having a capsule housing, the one or more electronics capsules includes an electronics unit within the capsule housing and a capsule cooling system. The capsule cooling system includes a capsule heat conductive interface in communication with the electronics unit.
In a MSCJ warhead detonation of the main charge is controlled to provide elevated pressure at multiple locations on the back surface of the liner to cut the liner and to form and propel forward a plurality of SCJs. An initiation system is configured for multi-point initiation of a plurality of booster charges to detonate the main charge to produce a plurality of detonation waves that constructively interfere at multiple locations on the back surface of the liner to form pressure hot spots that cut the liner and to form and propel forward a plurality of SCJs. In different embodiments, the elevated pressures are between 110% and 200% of the detonation pressure at the front of an individual detonation wave. The liner may, for example, include a plurality of recesses such as shallow dimples or deeper conical structures in which case the boosters are aligned to the center of the recessed structures.
