Ca, Mg, Zr, Gd and Ga garnet doped with Sm and melt method crystal growth method thereof

Abstract

The invention discloses a Ca, Mg, Zr, Gd and Ga garnet doped with Sm and a melt method crystal growth method thereof, the molecular formula thereof is Smz: Gd(3-x-z)CaxGa(5-x-2y)MgyZr(x+y)O12 (0<x<3,0<y<2.5, 0<z<3, 0<x+2y<5, 0<x+z<3), and the method comprises the following steps: the well-prepared raw materials are mixed fully, pressed and shaped, calcined in high temperature to obtain the starting raw material for crystal growth; the starting raw material is placed into a pot, heated and fully melt to obtain the initial melt of the melt method crystal growth, and is subjected to directionalor nondirectional growth on crystals by a melt method such as a traditional pulling method, a Bridgman-Stockbarge method, a flux growth method and the like to obtain solid laser working substances ofblue light pumping. By the invention, laser crystal with large size, even optical quality and fine performance can be obtained, which also can be used as solid laser working substances of blue light pumping and has the possibility of being used in fields such as medical diagnosis, material treatment, high density information reading and writing, monitoring and controlling, large screen color display, high definition color televisions and the like.

Description

technical field [0001] The invention relates to the field of laser materials and crystal growth, in particular to Sm-doped calcium magnesium zirconium gadolinium gallium garnet and its crystal growth method by melt method. Background technique [0002] Searching for new laser materials with excellent performance in the red band is an important topic in the fields of solid-state laser technology, material processing, high-density information reading and writing, monitoring and control, laser medicine, and color display. In laser display, red light is one of the three primary colors of red, green and blue. Among them, green laser technology is the most mature. Red light and blue light are still the focus of research. In terms of medical treatment, red light has a strong ability to penetrate tissues and can reach deep into tissues. Red light can treat chronic inflammation, endocrine disorders, nerve dysfunction and other diseases. In addition, red light can be used as a pum...

Problems solved by technology

Its disadvantage is that when the concentration of doped Sm is too high, the phenomenon of cross relaxation is more obvious, which is not conducive to the realization of laser output.
