摘要： The present invention provides octave-spanning optical frequency combs. The octave-spanning optical frequency combs employ microresonators having improved stability using a smaller form factor. In some embodiments, the octave-spanning optical frequency combs are fabricated using aluminum nitride (AlN). AlN is a more robust Kerr material for generating octave-spanning soliton comb (e.g., 1.5 octaves or more).

摘要： An optical resonator system comprises an optical resonator (30) and means (32, 42, 44) for coupling into the resonator counterpropagating waves at total intensities such as to produce a non-linear interaction between the first and second waves whereby to break the symmetry to establish different resonant frequencies between the first and second counterpropagating waves whereby to produce different optical effects in the opposite directions. A common light source, e.g. a laser 32, is employed with an amplifier 40 and a modulator 50, or different light sources can be employed.

摘要： Apparatuses and methods for supercontinuum generation using a laser beam and a plurality of condensed state transparent plates are presented. As an example, plate material to be used for one of the plurality of plates is determined. A thickness of the one of the plurality of plates is also determined. An allowable laser intensity of the laser beam is then determined to be λ/(2n0n2L), where λ is the central incident wavelength in vacuum, n0 is the linear refractive index, n2 is the third-order nonlinear coefficient. A location of a next plate is then determined to be a distance downstream from the one of the plurality of plates where a laser intensity of the laser beam returns to a value of the determined allowable laser intensity.

摘要： A method and an arrangement of spectrally broadening laser pulses for non-linear pulse compression is disclosed which is based on the transition from the spectral broadening in a waveguide to the spectral broadening in a suitably shaped lens conductor. The arrangement is non-sensitive with respect to the variations of the pulse power, the position and parameters of the laser beam. The spectrally broadened pulses can be compressed in a satisfactory manner and the quality of the laser beam maintained by dividing the non-linear phase required for spectral broadening into sufficiently smaller steps which can be separated without non-linearity by suitable prorogation. The limitation of the pulse powers to less than the critical power of dielectrics is thus overcome and a pulse energy range for which the spectral broadening in the glass fibres cannot be used, is developed. The arrangement can compress pulses having a large average power.

摘要： A mode-locked fiber MOPA delivers pulses of laser-radiation. A super-continuum generator including a bulk spectral-broadening element and a negative group-delay dispersion (NGDD) device is arranged to receive a pulse from the MOPA and cause the pulse to make a predetermined number of sequential interactions with the broadening element and the NGDD device. After making the predetermined interactions, the pulse is delivered from the super-continuum generator with a very broad spectral-bandwidth and a very short duration.

摘要： Nonlinear absorption of a sub-picosecond laser pulse is used to generate one or more spatially elongated heated gas volumes. Transient density variations caused by the spatially elongated heated gas volumes provide a refractive index profile capable of guiding electromagnetic radiation through the gas. The waveguide structure in the gas is disposed between the spatially elongated heated gas volumes and results from interaction between acoustic waves generated by the spatially elongated heated gas volumes or from a non-uniform thermal gas profile caused by the spatially elongated heated gas volumes. The nonlinear absorption can be repeated at regular intervals in time and space to renew the waveguide in the gas, thereby allowing for the guiding of high average power radiation (e.g., megawatts) that is well below self-focusing or stimulated Raman scattering thresholds. The spatially elongated heated gas volumes can be generated using remote focusing of sub-picosecond laser pulses and/or multiple sub-picosecond filaments.

摘要： Methods for producing a laser-guided underwater electrical discharge are provided. One or more electrodes defining a desired electrical discharge path are situated in a body of water and are attached to an external electrical power supply. A high-powered, intense laser beam is fired through one or more focusing lenses into the water. The laser beam forms an optical filament in the water, which in turn forms an ionized channel having a much greater conductivity than the surrounding water. An external power supply drives an electrical discharge along the path of the ionized channel due to its greater conductivity.
