Abstract
The invention relates to tuning rare earth ion emission wavelength in phosphate based glasses using cerium oxide, and specifically 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 1054nm. 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.
