- FIG. 2 is a diagram showing the result of X-ray diffraction showing the structure of the KAB crystal of the present invention.
- FIG. 3 is a diagram showing the result of X-ray diffraction similar to FIG. Best mode for carrying out the invention
- Non-linear optical crystal represented by K 2 AI 2 B 2 O 7 (can be abbreviated as KAB crystal) provided as the invention of this application.
- KAB crystal Non-linear optical crystal represented by K 2 AI 2 B 2 O 7
- the well-known SBB ⁇ crystal one or Ri, S r 2 K to S r site of B e 2 B 2 0 7 is, B e Size Lee Bok to AI Has a completely substituted structure.
- the KAB crystal of the present invention has a birefringence of 0.07, which is similar to that of a known SBB crystal. For this reason, generation of vacuum ultraviolet light can be expected. KAB crystals can be easily grown, for example, by a flux method or the like.
- the flux (simultaneous U) method is a kind of liquid phase growth method.
- TSSG Topic Seeded Solution Growth
- a seed crystal attached to a rotating shaft is immersed in the solution surface It is characterized by increasing the degree of supersaturation by temperature drop and growing crystals, and also by melting flux (flux) and raw materials.
- KA ⁇ crystals have a high melting point, it is preferable to grow them by the flux method (solution growth method) rather than the melt method (melt growth method). Yes.

- a sharp temperature gradient near the crucible is suppressed.
- the crucible is made of white gold, and the crucible base is moved up and down by an elevating device at the bottom of the furnace so that the raw material can be charged in a heated state.
- a solution surface heating heater to compensate for the temperature change on the solution surface, it is possible to prevent the temperature drop due to evaporation near the liquid surface and to optimize the temperature distribution for growth. It is devised so that it can be obtained. At a temperature of about 100 ° C, it dissolves in the atmosphere of the atmosphere, They were cooled to grow microcrystals. The temperature drop rate was 0.2 to 0.3 ° CZ day, and the rotation speed was 30 rpm (reversed every 3 minutes).
- this crystal has a composition of K 2 AI 2 B 2 O 7 , and its crystal structure is shown in four axes in FIGS. 2 and 3.
