摘要:
借助于顶端籽晶溶液法,采用[110]和[111]方向籽晶生长了大尺寸高质量三硼酸铋(BiB_3O_6,BIBO)单晶,尺寸为30mm×30mm×40mm,最大晶体质量接近100g。用X射线衍射和偏光显微镜确定折射率主轴方向与结晶轴方向x//b,(y,c)=47.2°,(z,a)=31.6°。根据折射率色散方程计算了位相匹配方向,实验确定1064 nm激光倍频方向(168.9,°90°),三倍频方向(146.4°,90。),946 nm激光的倍频方向(161.9°,90°)。以2.4 mm和6 mm长BIBO晶体实现了1064 nm激光的倍频和三倍频,效率分别为67.7%和39.5%(10 Hz,35 ps);以5 mm长的BIBO晶体分别在钛宝石激光器和LD泵浦Nd:YAG准连续激光器实现了946 nm到473 nm的激光输出,总效率分别为5.2%和4.8%,后者采用10 mm的LBO晶体作对比,其总效率为2.7%。讨论了晶体生长中遇到的主要问题及其解决办法,并指出BIBO的抗光损伤阈值是值得重视的问题。

Large size and high quality BiB3O6(BIBO) crystal was grown with [110]or [111] orientated seeds by using top see-ded solution growth method. The crystal size is 30 mm×30 mm×40 mm, and the mass of the crystal is up to about 100 g. The relative orientation of main refractive index axes to crystallographic axes is determined to be x//b, (y, c) = 47. 2°, (z, a) = 31. 6° by means of X-ray diffraction and polarized microscopy. According to the Sellmeier equations of BIBO crystal, the phase-matching angles for second harmonic generation(SHG) and third harmonic generation(THG) have been calculated and the sam-ples of BIBO for phase-match (PM) experiments were prepared on the basis of the calculation. The optimal PM angles for 1064 nm SHG and THG are (168. 9°, 90°)and (146. 4°, 90°), respectively and for 946 nm SHG is (161. 9°, 90°) , which are all determined experimentally. The SHG and THG for l 064 nm (10 Hz, 35 ps) were performed in a 2. 4 mm long and 6 mm long BIBO sample respectively. The conversion efficiencies are 67. 7% for SHG and 39. 7% for THG. The SHG for 976 nm to 473 nm blue light has been realized by using Ti : Al2O3 laser and LD pumped Nd: YAG laser, in a 5mm long BIBO crystal, the total efficiencies are 5. 2%and 4. 8% respectively. For comparison, a 10 mm long LBO crystal was used in LD pumped Nd: YAG laser and the total efficiency is 2. 7%. Finally, the problems in crystal growth and the way to solve them have been dis-cussed. It is pointed out that the damage threshold of BIBO is substantial for the applications of BIBO crystal.
