 new patent  Systems and methods for low noise frequency multiplication, division, and synchronization

Low phase noise radio frequency (RF) sources generated by voltage controlled oscillators (VCOs) are described. Optical modulators driven by a VCO may be used to generate optical side-bands to cw lasers. The spectral extent of said side-bands can be increased via frequency broadening in highly nonlinear waveguides. Free running mode... Imra America Inc

Single mode propagation in fibers and rods with large leakage channels

Various embodiments include large cores fibers that can propagate few modes or a single mode while introducing loss to higher order modes. Some of these fibers are holey fibers that comprise cladding features such as air-holes. Additional embodiments described herein include holey rods. The rods and fibers may be used... Imra America Inc

Large core holey fibers

Holey fibers provide optical propagation. In various embodiments, a large core holey fiber comprises a cladding region formed by large holes arranged in few layers. The number of layers or rows of holes about the large core can be used to coarse tune the leakage losses of the fundamental and... Imra America Inc

Laser-based modification of transparent materials

The present disclosure provides examples of a laser-based material processing system for liquid-assisted, ultrashort pulse (USP) laser micromachining An example material processing application includes drilling thru-holes or blind holes in a nearly transparent glass workpiece (substrate) using parallel processing with an n×m array of focused laser beams. Methods and systems... Imra America Inc

Glass large-core optical fibers

Embodiments of optical fiber may include cladding features that include a material (e.g., fluorine-doped silica glass) that may produce a very low relative refractive index difference with respect to cladding material in which the cladding features are disposed. This relative refractive index difference may be characterized by (n1−n2)/n1, where n1... Imra America Inc

Gold nanoparticle-based homogeneous colorimetric diagnostic assay for the detection of proteases and protease inhibitors

In the present invention, a method and assay for the detection of proteases and protease inhibitors using colloidal gold nanoparticles and peptide substrates, which are selectively recognized and cleaved by proteases being assayed, is disclosed. In this assay, the mechanism of signal generation relies on peptide sequence induced aggregation of... Imra America Inc

Transparent material processing with an ultrashort pulse laser

A method for scribing transparent materials uses ultrashort laser pulses to create multiple scribe features with a single pass of the laser beam across the material, with at least one of the scribe features being formed below the surface of the material. This enables clean breaking of transparent materials at... Imra America Inc

Low carrier phase noise fiber oscillators

The present disclosure relates to the design of fiber frequency comb lasers with low carrier phase noise. Examples of these low carrier phase noise oscillators can be constructed from both soliton and dispersion compensated fiber lasers via the use of intra-cavity amplitude modulators such as graphene modulators. In low carrier... Imra America Inc

Yb: and nd: mode-locked oscillators and fiber systems incorporated in solid-state short pulse laser systems

The invention describes classes of robust fiber laser systems usable as pulse sources for Nd: or Yb: based regenerative amplifiers intended for industrial settings. The invention modifies adapts and incorporates several recent advances in FCPA systems to use as the input source for this new class of regenerative amplifier.... Imra America Inc

Compact ultra-short pulse source amplifiers

The present invention relates to compact, low noise, ultra-short pulse sources based on fiber amplifiers, and various applications thereof. 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.... Imra America Inc

Inexpensive variable rep-rate source for high-energy, ultrafast lasers

System for converting relatively long pulses from rep-rate variable ultrafast optical sources to shorter, high-energy pulses suitable for sources in high-energy ultrafast lasers. Fibers with positive group velocity dispersion (GVD) and self phase modulation are advantageously employed with the optical sources. These systems take advantage of the need for higher... Imra America Inc

Pulsed laser sources

Modelocked fiber laser resonators may be coupled with optical amplifiers. An isolator optionally may separate the resonator from the amplifier. A reflective optical element on one end of the resonator having a relatively low reflectivity may be employed to couple light from the resonator to the amplifier. Enhanced pulse-width control...
