Embodiment Construction

[0024] For the growth device of the composite laser material used in the present invention, see figure 1 , is a high-temperature autoclave with an external heat-insulating cover and a matching temperature-difference well-type resistance furnace 10. Its structure mainly includes: growth area 1, dissolution area 2, steel cap 3, steel kettle 4. In order to prolong the life of the autoclave and prevent the acid or alkaline solution from corroding the inner wall of the autoclave under high temperature and pressure, a gold bushing 5 is used as a protective bush to separate from the inner wall of the autoclave. Use the trapezoidal seed crystal frame 6 that gold wire is made, the seed wafer that cuts by certain direction is connected with gold wire and is fixed on the seed crystal frame 6, every time a trapezoidal frame can hang dozens of pieces (depending on the size of the seed crystal) Certainly). Gold bushing 5 inner chamber has H 2 O+ Mineralizer 7, YVO 4 The culture material...

Abstract

A growth method of neodymium-doped yttrium vanadate and yttrium vanadate composite laser crystals, which is formed by growing non-doped yttrium vanadate single crystals at both ends of neodymium-doped yttrium vanadate single crystals by using a hydrothermal growth furnace, and the crystal integrity Well, it is cut and processed to make a laser, which has broad application prospects in the field of miniaturized, high-efficiency, and low-threshold solid-state lasers.

Description

Technical field: [0001] The present invention relates to laser crystal, particularly a kind of neodymium-doped yttrium vanadate (Nd:YVO 4 ) and yttrium vanadate (YVO 4 ) compound laser crystal growth method, specifically related to the growth of non-doped yttrium vanadate at both ends of a neodymium-doped yttrium vanadate single crystal, combined into a composite laser crystal material of neodymium-doped yttrium vanadate and yttrium vanadate: YVO 4 / Nd:YVO 4 / YVO 4 . Background technique: [0002] Neodymium-doped yttrium vanadate (Nd:YVO 4 ) crystals have a zircon-type structure. As a matrix material, the crystal has attracted the attention of academic circles as early as the 1960s and 1970s due to its low pumping threshold, large laser emission cross-section, and continuous operation of 1.34 μm and 1.06 μm lasers. Evaluation, in the early 1990s, due to the great progress in the research of laser diodes (LD), LD may be put into application as a pump source for miniatur...
