Solid body

Abstract

Solid body for the production of solid-state lasers, the solid body having, at least in an optically used area, monoclinic elementary cells based on the same crystallographic system of coordinates, and having in the optically used area at least two domains with different chemical compositions, the optically used area having at least one active zone and at least one non-active zone. At least in the optically used area, at least one of tungstenate, potassium, and rubidium may be a constituent of the monoclinic elementary cells. At least in the optically used area, at least one of Y, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu may be a constituent of the monoclinic elementary cells. Solid body is suited for a device for generating coherent electromagnetic radiation, such as a laser beam. The solid body may be used as a disk or chip laser.
