Abstract

Device for emitting fluoresence and amplified radiation has a transparent, piezo-electric crystal with a piezo axis. The crystal is doped with ions of atoms which are heterogenic in relation to the crystal lattice. A piezo drive body is situated near the crystal and forms a single one-piece device with it. The piezo-drive body is coupled mechanically to the crystal and exerts a mechanical pressure on it to produce a direct piezo-electrical effect. The piezo drive has a piezo axis oriented to the crystal axis to produce a converse piezo-electric effect in the crystal. Both the direct and converse piezo-electric effects are directed against each other, and oppose each other in the crystal. Devices are provided to attach an a.c. source to the crystal and to the piezo-drive body.
