Abstract: The present invention relates to a trace gas detection system. At least one embodiment includes a frequency spectrum comprising a 1 st comb and an enhancement cavity characterized by having a 2 nd comb of spectral resonances. The enhancement cavity contains a sample gas for spectroscopic measurement. A dither mechanism is configured to modulate the relative spectral position between the combs at a dither frequency, f d . The dither mechanism, in conjunction with a feedback mechanism, stabilizes the location of said 1st comb lines with respect to the resonances of said 2 nd comb over a time scale much greater than a dither period, T d = 1/f d . A time- averaged output from the enhancement cavity is provided to a spectroscopic measurement tool, for example a Fourier transform spectrometer. The system is capable of detecting volatile organic compounds, endogenous compounds, and may be configured for cancer detection.

At least one implementation includes an optical amplification system having a fiber laser seed source producing seed pulses at a repetition rate corresponding to the fiber laser cavity round trip time. A nonlinear pulse transformer, comprising a fiber length greater than about 10 m, receives a seed pulse at its input and produces a spectrally broadened output pulse at its output, the output pulse having a spectral bandwidth which is more than 1.5 times a spectral bandwidth of a seed pulse. A fiber power amplifier receives and amplifies spectrally broadened output pulses. A pulse compressor is configured to temporally compress spectrally broadened pulses amplified by said power amplifier.

Abstract: Compact high brightness light sources for the mid and far IR spectral region, and exemplary applications are disclosed based on passively mode locked Tm fiber comb lasers. In at least one embodiment the coherence of the comb sources is increased in a system utilizing an amplified single-frequency laser to pump the Tm fiber comb laser. The optical bandwidth generated by the passively mode locked Tm fiber comb laser is further decreased by using simultaneous 2nd and 3rd order dispersion compensation using either appropriate chirped fiber Bragg gratings for dispersion compensation, or fibers with appropriately selected values of 2nd and 3rd order dispersion. Fibers with large anomalous values of third order dispersion, or fibers with large numerical apertures, for example fibers having air-holes formed in the fiber cladding may be utilized.

Abstract: In the present invention, a method of producing stable bare colloidal gold nanoparticles is disclosed. The nanoparticles can subsequently be subjected to partial or full surface modification. The method comprises preparation of colloidal gold nanoparticles in a liquid by employing a top-down nanofabrication method using bulk gold as a source material. The surface modification of these nanoparticles is carried out by adding one or multiple types of ligands each containing functional groups which exhibit affinity for gold nanoparticle surfaces to produce the conjugates. Because of the high efficiency and excellent stability of the nanoparticles produced by this method, the fabricated gold nanoparticle conjugates can have surface coverage with functional ligands which can be tuned to be any percent value between 0 and 100%.

Abstract: At least one embodiment of the present invention provides preparation methods and compositions for nanoarchitectured multi-component materials based on carboncoated iron-molybdenum mixed oxide as the electrode material for energy storage devices. A sol-gel process containing soluble organics is a preferred method. The soluble organics could become a carbon coating for the mixed oxide after thermal decomposition. The existence of the carbon coating provides the mixed oxide with an advantage in cycling stability over the corresponding carbon-free mixed oxide. For the carbon-coated mixed oxide, a stable cycling stability at high charge/discharge rate (3A/g) can be obtained with Mo/Fe molar ratios ≥ 1/3. The cycling stability and rate capability could be tuned by incorporating a structural additive such as Al 2 O 3 and a conductive additive such as carbon nanotubes. The high rate performance of the multi-component material has been demonstrated in a full device with porous carbons as the positive electrode material.

At least one implementation provides for seeding of a solid state amplifier or large core fiber amplifier with time delayed, polarization split pulses, with capability for recombining the time separated pulses at an amplifier output. In various implementations suitable combinations of bulk optics and fibers may be utilized. In some implementations wavelength converted pulse trains are generated.
