Abstract

The invention discloses a multifunctional caesium lanthanum molybdate crystal as well as a preparation method and an application thereof and belongs to the technical field of artificial crystals. The chemical formula of the caesium lanthanum molybdate crystal is CsLa(1-x)Ndx(MoO4)2, wherein the doping concentration of Nd is larger than or equal to 0 and smaller than or equal to 0.15. Cs2MoO4 is taken as a flux, the mole ratio of the flux to CsLa(1-x)Ndx(MoO4)2 is 0.2-3, and the high-quality CsLa(1-x)Ndx(MoO4)2 crystal with a larger size is obtained through growing with a flux method at the cooling speed of 0.5-3 DEG C per day and at the rotating speed of 5-30 revolutions per minute. The caesium lanthanum molybdate crystal can be taken as a laser crystal to generate laser, can also be taken as a Raman crystal to perform Raman frequency conversion on the laser and can further be taken as a self-Raman laser crystal with a composite function for manufacturing of integrated, small and multi-wavelength lasers. A solid laser prepared from the crystal can be used for multiple fields such as military, medical treatment, remote sensing, ocean exploration and the like.

Description

technical field

[0001] The invention relates to the technical field of artificial crystals, in particular to a multifunctional cesium lanthanum molybdate crystal and its preparation method and application. Background technique

[0002] Laser crystal is the working substance of solid-state laser. It refers to the luminescent material that uses crystal as the matrix to absorb pump light energy and convert it into laser output through discrete luminescent centers. The solid-state laser working substance is composed of matrix material and active ions. Its various physical and chemical properties are mainly determined by the matrix material, while its spectral characteristics and fluorescence lifetime are determined by the energy level structure of the active ion. Neodymium ions have good spectral properties and are one of the most important active ions in the field of laser crystals. The most widely used laser crystal is yttrium aluminum garnet (YAG) crystal doped with neodymiu...
