The present disclosure relates to compositions that can be used for optical fibers and other systems that transmit light in the near-, mid- and/or far-ranges of the infrared spectrum, such as for example in the wavelength range of 1.5 &#x3bc;m to 14 &#x3bc;m. The optical fibers may comprise a light-transmitting chalcogenide core composition and a cladding composition. In some embodiments, the light-transmitting chalcogenide core composition has a refractive index n(core) and a coefficient of thermal expansion CTE(core), and the cladding composition has a refractive index n(cladding) and a coefficient of thermal expansion CTE(cladding), wherein n(cladding) is less than n(core) and in some embodiments wherein CTE(cladding) is less than CTE(core). In some embodiments, the chalcogenide glass core composition comprises a) sulfur and/or selenium, b) germanium, and c) gallium, indium, tin and/or one or more metal halides.

Chalcogenide compositions for optical fibers and other systems

The disclosure relates generally to optical systems, and more particularly, optical systems for temporal compression or stretching of optical pulses.

Devices, systems, and methods for temporal compression or stretching of optical pulses

The invention relates to chalcogenide glass compositions for use in a lens system to balance thermal effects and chromatic effects and thereby provide an achromatic and athermal optical element that efficiently maintains achromatic performance across a broad temperature range. The glass composition is based on sulfur compounded with germanium, arsenic and/or gallium, and may further comprise halides of, for example, silver, zinc, or alkali metals. Alternatively, is based on selenium compounded with gallium, and preferably germanium, and contains chlorides and/or bromides of, for example, zinc, lead or alkali metals.

Glasses for the correction of chromatic and thermal optical aberations for lenses transmitting in the near, mid, and far-infrared spectrums

The invention relates to infrared devices, which contain at least two optical elements that are bonded together by a low-temperature melting glass which possesses transparency in the infrared spectrum, and methods of preparation and use of said infrared devices.

Optical bonding through the use of low-softening point optical glass for IR optical applications and products formed

A glass composition and a method for producing the glass composition having an improved infrared transmission are provided. The composition includes indium and or cadmium; germanium; phosphorus, arsenic, and/or antimony; silver; lead; and sulfur, selenium, and/or tellurium. The method is performed by melting a mixture for a time period of between about 5 to about 48 hours and mixing the mixture at a temperature range that is between about 600-1000&#xb0; C.

Infrared transmission chalcogenide glasses

The invention relates to an optical fiber comprising a core and a cladding, wherein the core is made of a glass composition having a near-zero electrostrictive coefficient M, to reduce the effect of stimulated Brillouin Scattering (SBS). The invention further relates to a compensation fiber segment for connection to a silica optical fiber, the compensation fiber segment being made of a glass composition having an electrostrictive coefficient that opposes that of the silica optical fiber so that an acoustic wave transmitted to compensation fiber segment from the silica optical fiber will generate an acoustic wave within the compensation fiber segment that is about 180 degrees out of phase with the that acoustic wave transmitted from the silica optical fiber, thereby minimizing the effect of stimulated Brillouin Scattering.

Optical fiber for the reduction of stimulated Brillouin scattering in high-power applications

The invention relates to a Nd-doped, aluminate-based or silicate-based, laser glass having a peak emission wavelength that is longer than 1059.7 nm, an emission cross section (&#x3c3;) of &#x2267;1.5&#xd7;10cm, and/or an emission bandwidth (&#x394;&#x3bb;) of &#x2267;28 nm, while maintaining properties that render the glass suitable for commercial use, such as low glass transition temperature Tand low nonlinear index, n.

Glasses for the correction of chromatic and thermal optical aberations for lenses transmitting in the near, mid, and far-infrared sprectrums

The invention relates to a Nd-doped (and/or Yb-doped and/or Er-doped) phosphate laser glass having a peak emission wavelength that is shorter than 1054 nm. Cerium oxide (CeO) is incorporated into a phosphate glass host system, preferably in replacement of lanthanum oxide, to shift the peak emission wavelength to a wavelength shorter than 1054 nm. The invention further relates to a laser system using mixed-glass arrangement and phase compensation, wherein one of the glasses of the mixed glass system is an Nd-doped (and/or Yb-doped and/or Er-doped) phosphate laser glass having a peak emission wavelength that is shorter than 1054 nm, and a method of generating a laser beam pulse using such a laser system.

Tuning rare earth ion emission wavelength in phosphate based glasses using cerium oxide

The invention relates to glasses for use in solid laser applications, particularly short-pulsed, high peak power laser applications. In particular, the invention relates to a method for broadening the emission bandwidth of rare earth ions used as lasing ions in solid laser glass mediums, especially phosphate-based glass compositions, using Nd and Yb as co-dopants. The invention further relates to a laser system using a Nd-doped and Yb-doped phosphate laser glass, and a method of generating a laser beam pulse using such a laser system.
