| 20120033686 | ALL-GAIN GUIDING YB-DOBED FEMTOSECOND FIBER LASER - A mode-locked fiber laser system is presented with an improved optical cavity structure having a lower doped and longer gain medium. The laser system comprises: a laser source operable to produce a light beam; an optical cavity structure operable to amplify a light beam propagating therethrough; and a beam splitter operable to output the amplified light beam from the optical cavity. The optical cavity includes a single-mode fiber section and a gain fiber section doped with a lanthanide element, such as erbium or ytterbium, where the ratio between length of the gain fiber section to a total length of the cavity structure is greater than 1:5. By increasing length of the gain medium, peak power of the generated pulse is increased while keeping the nonlinear phase shift constant to avoid optical wave breaking. | 02-09-2012 |
| 20100014077 | METHOD FOR USING A PHOTONIC CRYSTAL FIBER AS A RAMAN BIOSENSOR - A method is provided for biosensing using a photonic crystal fiber having a hollow core. The method includes: designating an analyte of interest; determining a wavelength for an excitation light source which generates a Raman spectrum when incident upon the analyte of interest; selecting a photonic crystal fiber that would guide the light when the fiber is non-selectively filled with a solvent hosting the analyte of interest; non-selectively filling a photonic crystal fiber with the solvent hosting the analyte of interest; interrogating the analyte of interest by coupling light from the light source to the photonic crystal fiber; and analyzing the light output from the photonic crystal fiber for Raman fingerprints. | 01-21-2010 |
