研究了ＹｂｘＹ１－ｘＡｌ３（ＢＯ３）４（Ｙｂ∶ＹＡＢ）晶体的生长及光学性质，结果表明，以Ｋ２Ｍｏ３Ｏ１０作为助熔剂生长Ｙｂ∶ＹＡＢ晶体效果较好，根据测定的Ｙｂ∶ＹＡＢ折射率计算的一类位相匹配角为θｍ（Ⅰ）＝３４°１２′，与实验测定值θｍ（Ⅰ）＝３４°３８′吻合较好。该晶体室温吸收谱在９５６和９７５ｎｍ处存在两个吸收带，适于ＩｎＧａＡｓ泵浦；室温π偏振吸收比σ偏振吸收略强；１０３和１０４μｍ处各存在一荧光峰，１０３μｍ处荧光寿命为１３７９ｍｓ；估算的发射截面数量级为１０－２１ｃｍ２
The growth and optical properties of YbxY1-xAl3 (BO3) 4 (Yb: YAB) crystal were studied. The results show that the Yb:YAB crystal with K2Mo3O10 as a flux has good effect. According to the measured Yb: YAB index, The phase matching angle is θm (I) = 34 ° 12 ’, which is in good agreement with the experimental value θm (I) = 34 ° 38’. There are two absorption bands at 956 and 975 nm for the absorption spectrum of the crystal at room temperature, which is suitable for InGaAs pumping. At room temperature, the π-polarization absorption is slightly stronger than that of σ-polarization absorption. There is a fluorescence peak at 103 and 104 μm, The fluorescence lifetime is 1 379 ms; the estimated emission cross section is on the order of 10-21 cm 2
