Embodiment

[0068] Table 1 lists the La 2 o 3 Nd-doped phosphate-based glasses (LaNd) and containing CeO 2 Nd-doped phosphate glass according to the invention. Table 2 lists the lasing properties of the two compositions.

[0069] All glasses are manufactured using laser-grade ingredients and melted with agitation in a dry oxygen atmosphere using a platinum stirrer for good homogeneity. All glasses were cast into molds and properly annealed to remove stress as the liquid cooled to the amorphous state. The resulting glass sheet is shaped into the form desired for use in tools that provide various glass properties.

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.

Description

technical field [0001] The present invention relates to glasses for use in solid state laser applications, particularly short pulse high peak power laser applications. In particular, the present invention relates to glasses for hybrid glass laser systems in which phosphate laser glasses are used in combination with aluminate or silicate laser glasses. In addition, the present invention relates to an Nd-doped phosphate glass suitable for use in hybrid glass laser systems, wherein the Nd-doped phosphate glass has a peak emission at shorter wavelengths, ie wavelengths below 1054 nm. Additionally, the present invention relates to a method of shifting the peak emission wavelength of Nd-doped phosphate glasses to shorter wavelengths without adversely affecting (ie, narrowing) the emission bandwidth. Background technique [0002] A general trend in solid-state lasers is to make high-energy lasers with shorter pulse lengths, which allow very high values ​​of power in the pulses. F...
