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 (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.

The invention relates to an optical scattering element suitable for dispersing or scattering light transmitted by optical device by Mie scattering. The optical scattering element comprises a phase-separated or porous borosilicate glass having dispersed phase particles with a particle size of 200 to 500 nanometers or pores with a size of 200 to 500 nanometers, at a number density of 108 to 1012 mm−3. The optical scattering element can be prepared by subjecting a borosilicate glass to a controlled heat treatment to induce phase separation, and then optionally leaching out one of the phases with an acid leach. The optical scattering element can be, for example, attached to an end of an optical fiber or bundle of optical fibers. The invention also relates to a method of dispersing or scattering light by transmitting the light through the optical scattering element.

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.
