US Classification:

Abstract:

A pulsed coherent fiber array laser system that includes a beam generating sub-system that provides a signal pulse beam having pulses of the desired duration that is split into several fiber channels. Optical leakage between the pulses in each split beam is measured and locked to a reference beam by a phase sensing circuit and phase adjusters so that the phase of each fiber pulsed beam is aligned with the phase of the reference beam. A pulse clipper or filter is employed to remove the pulses in the fiber beams so that they do not saturate the phase sensing circuit. The beam generating sub-system can employ any suitable combination of devices to generate the signal beam and the reference beam, including continuous wave master oscillators, amplitude modulators, frequency shifters, injection seed oscillators, Q-switched lasers, reference oscillators, frequency lockers, wavelength division multiplexers, time gated switches, etc.

Abstract:

Disclosed is a modular system for displaying articles, providing a working surface for a worker, or both in a retail or exhibition environment. The modular system comprises a plurality of blocks configurable to form structures without fastening means therebetween, each block having a shape of a generally rectangular cuboid. The dimensions of each block are configured to form the structures based on stacking, aligning, placing, arranging, tilting, slanting, or a combination thereof.
