A system includes a first AC power meter configured to measure a first real AC power at an output of a source of AC power on an AC power line. The system further includes an energy storage system configured to at least supply AC power to the AC power line. The system further includes a second AC power meter configured to measure a second real AC power at a junction between the energy storage system and an AC power line. The system further includes a first direct AC electrical path from the energy storage system through the second AC power meter to the AC power line. The system further includes a controller configured to control the source of the AC power to the AC power line based on the measured first and second real power to maintain the target AC power level on the AC power line.

A low-cost, high performance cladding-pumped planar waveguide amplifier and fabrication method, for deployment in metro and access networks. The waveguide amplifier has a compact monolithic slab architecture preferably formed by first sandwich bonding an erbium-doped core glass slab between two cladding glass slabs to form a multi-layer planar construction, and then slicing the construction into multiple unit constructions. Using lithographic techniques, a silver stripe is deposited and formed at a top or bottom surface of each unit construction and over a cross section of the bonds. By heating the unit construction in an oven and applying an electric field, the silver stripe is then ion diffused to increase the refractive indices of the core and cladding regions, with the diffusion region of the core forming a single mode waveguide, and the silver diffusion cladding region forming a second larger waveguide amenable to cladding pumping with broad area diodes.

Large neodymium glass laser disks for disk amplifiers such as those used in the Nova laser require an edge cladding which absorbs at 1 micrometer. This cladding prevents edge reflections from causing parasitic oscillations which would otherwise deplete the gain. Nova now utilizes volume-absorbing monolithic-glass claddings which are fused at high temperature to the disks. These perform quite well but are expensive to produce. Absorbing glass strips are adhesively bonded to the edges of polygonal disks using a bonding agent whose index of refraction matches that of both the laser and absorbing glass. Optical finishing occurs after the strips are attached. Laser disks constructed with such claddings have shown identical gain performance to the previous Nova disks and have been tested for hundreds of shots without significant degradation.

A size-adjustable jump-rope exercising apparatus comprising a framework structure having a substantially 'H'-shaped configuration wherein the framework is formed having spaced, parallel, longitudinally extended, side-frame members. The frame members are connected together intermediate their free ends by a transverse strut member by which the width of the apparatus can be adjusted and which includes gripping handles whereby the user thereof holds the apparatus for rotation about the longitudinal axis of the strut member when the strut member is positioned in a horizontal mode. Mounted at each free end of the side member is an elongated rod member adjustably mounted longitudinally therein and a flexible rope which is looped across from the outer end of one rod member to the other, defining a closed-loop, jump structure having dual jumping ends.
