The invention relates to phosphate-based glasses suitable for use as a solid laser medium, doped with Er3+ and sensitized with Yb, in 'eye-safe' applications. In particular, the invention relates to improving the physical properties of such phosphate-based laser glass composition, particularly with regards to strength of the glass structure and improved thermal shock resistance.

Aluminophosphate glass composition

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.

Broadening the rare earth ion emission bandwidth, increasing emission cross section, and or shifting peak emission wavelength in nd doped aluminate or silicate glasses

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.
