  • Patent number: 11851368
    Abstract: An optical nanocomposite containing optically active crystals and suitable to be drawn into fiber form, dissolved into solution and subsequently deposited as a thin film, or used as a bulk optical component. This invention integrates compositional tailoring to enable matching of optical properties (index, dispersion, do/dT), specialized dispersion methods to ensure homogeneous physical dispersion of NCs within the glass matrix during preparation, while minimizing agglomeration and mismatch of coefficient of thermal expansion. By tailoring the base glass composition's viscosity versus temperature profile, the resulting bulk nanocomposite can be further formed to create an optical fiber, while maintaining physical dispersion of NCs, avoiding segregation of the NCs.

  • Publication number: 20200079683
    Abstract: An optical nanocomposite containing optically active crystals (rare earth or transition metal doped) in a suitably index-, dispersion-, thermo-optically matched matrix enables creation of a glass ceramic with unique optical properties. By further tuning the viscosity of the composite, it can be drawn into fiber form, dissolved into solution and subsequently deposited as a thin film, or used as a bulk optical component. Critical to achieving a viable material is closely matching the attributes needed to not only achieve optical function but to enable fabrication under elevated temperatures (i.e., during fiber drawing) or in unique chemical or thermal environments, such as during deposition as a thin film. This invention uses nanosized crystalline powders (nanocrystals—NC), blended with multicomponent chalcogenide glass (ChG) to form an optical nanocomposite.

  • Patent number: 7881347
    Abstract: Methods and systems for hybrid gain guiding in laser resonators that combines the features of gain guiding and fiber or other types of lasers into a single system. Hybrid gain guiding in laser resonators is not limited to conventional fiber lasers. Any type of gain guided fiber, index guided or anti-guided, is used as an intracavity element to induce loss on high order modes in an otherwise multimode laser system. The gain guided element contributes little gain to the laser oscillator but allows only the lowest order mode to transmit without loss. When the gain guiding fiber length is selected so the loss for a particular cavity mode is greater than the gain, the cavity mode does not lase. Since the gain guiding fiber induces loss for all laser modes other than the lowest order mode it makes sure that the mode one higher than the lowest order mode does not lase and as a result, no other cavity modes lase.

The optical imaging step includes activating a light source to image the generated target, the light source is strobed at approximately the same rate as the droplet production to provide illumination of the droplet for stroboscopic imaging. The step of moving is accomplished mechanically by moving the generated target back to the predefined position or electronically under computer control.

  • Patent number: 7668211
    Abstract: Methods, systems and devices for a waveguide pumping gain guided index antiguided fiber laser having a fiber selected for a refractive index crossover at a wavelength between a pump wavelength and a laser emission wavelength. A waveguide pumping system pumps a light having a pump wavelength into the fiber allowing a laser light to be captured by a gain guided process in the core while the pump light, propagating in the cladding is coupled to the core. The fiber selection includes selecting a fiber with a cladding material having a refractive index less than a core material refractive index for a pump wavelength and a core refractive index at the laser emission wavelength is less than the cladding refractive index at the same laser emission wavelength to allow the pump light to propagate through the cladding as a conventional wave guided fiber laser, white the laser emission is captured within the core as an index antiguided, gain guided wave.

The systems, devices and methods of using stable, self-starting mode-locked lasers, can be compact, use fewer optical elements and have energies sufficient for most micro-processing and micro-structuring applications. The large spectral bandwidth of ultra-short (femtosecond) laser pulses can be used in laser sensing applications, micro-machining, time-resolved experiments, where short-lived transient species can be observed in biological or chemical reactions. Terahertz radiation can be generated using ultrashort pulses and used for imaging applications.

  • Patent number: 7551267
    Abstract: Systems and methods for measuring a pulse length (?0) of an ultra-short light pulse (P0) based on processing a number of substantially similar light pulses. The system includes an autocorrelation optical system adapted to receive the light pulses P0 and create from each light pulse two beams having an associated optical path length difference ?OPL. Providing a different ?OPL for each light pulse creates an autocorrelation interference pattern representative of an autocorrelation of the light pulse P0. An LED detector detects the autocorrelation interference pattern and generates therefrom an autocorrelation signal. A signal-processing unit forms from the autocorrelation signal a digital count signal representative of a number of counted peaks in the autocorrelation signal above the full-width half maximum. Control electronics unit causes the varying ?OPL and provides a difference signal (S?) representative of the ?OPL to the signal-processing unit.
