Abstract: 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 M11, 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.

Cerium oxide (CeO2) 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.
