International Classification:

H04J 14/02
G02B 27/64

US Classification:

359556, 398 87

Abstract:

Apparatus and method for spectral-beam combining light from a plurality of high-power fiber lasers that, in some embodiments, use two substantially identical diffraction gratings in a parallel, mutually compensating configuration to combine a plurality of separate parallel input beams each having a slightly different successively higher wavelength into a single output beam of high quality. In other embodiments, a single diffraction grating is used to combine a plurality of different wavelengths, wherein the input laser beams are obtained from very narrow linewidth sources to reduce chromatic dispersion. In some embodiments, diagnostics and adjustments of wavelengths and/or positions and angles are made dynamically in real time to maintain the combination of the plurality input beams into a single high-quality output beam.

International Classification:

H01S 4/00
H04B 10/17

US Classification:

359349

Abstract:

Apparatus and method for spectral-beam combining of light from a plurality of high-power lasers (e. g. , fiber MOPA lasers) that, in some embodiments, use substantially identical diffraction gratings in a 1-D non-parallel, mutually compensating configuration to combine non-parallel converging input beams in one plane each having a slightly different successively higher wavelength into a single output beam of high quality. In other embodiments, an output grating and one or more input gratings in a 1-D parallel, mutually compensating configuration combine non-parallel input beams in one plane into a single output beam of high quality. In other embodiments, a 2-D plurality of input gratings in a non-parallel configuration combine a plurality of non-parallel input beams not in one plane each having a slightly different successively higher wavelength into a set of converging beams in one plane directed towards an output grating that compensates for chromatic dispersions introduced by the input gratings.

US Classification:

359556

Abstract:

A ring-laser system that includes a plurality of ring-laser gain elements and a spectral-beam-combining output stage configured to combine a plurality of beams coming from the gain elements into an output beam and that includes chromatic-dispersion compensation. In some embodiments, the output stage includes a plurality of highly reflective dielectric-coated focussing elements. In some embodiments, the output stage includes a plurality of high-efficiency dielectric-coated grating elements. In some embodiments, the output stage includes a mostly reflective but partially transmissive output mirror and a highly reflective beam-reversing mirror configured to reflect a majority of a backward-traveling signal beam such that it becomes forward traveling. In some embodiments, each gain element further includes a photonic-crystal-rod power amplifier. Some embodiments have an amplitude modulator configured to pulse the plurality of beams, and a timing controller configured to synchronize the pulses of the plurality of beams.

International Classification:

A61K031/365

US Classification:

514/473000

Abstract:

This invention provides a method for inducing weight loss in an animal by administering to the animal a compound which reduces the expression and/or secretion of neuropeptide Y (NPY). The effect may be accomplished directly, indirectly or humorally. Preferably, administration of this compound has the effect of increasing malonyl CoA levels in the animal. Compounds administered according to this invention may be inhibitors of fatty acid synthase (FAS), including substituted -methylene--carboxyl--butyrolactones, or inhibitors of malonyl Coenzyme A decarboxylase (MCD). Preferably, the compound is administered in an amount sufficient to reduce the amount and/or duration of expression and/or secretion of NPY to levels at or below those observed for lean animals. In another preferred embodiment, the administration will reduce expression and/or secretion to levels observed for fed or satiated animals; more preferably, administration will reduce the level of NPY below that of fed animals. In a particular embodiment, this invention provides a method for inducing weight loss in an animal by administering a compound which inhibits feeding behavior in the animal. The method is particularly useful for inducing weight loss in animals deficient in expression of the hormone leptin or animals resistant to the action of leptin.
