摘要: 高温相α-BBO晶体是一种理想的紫外双折射晶体,但晶体生长过程中容易存在残余应力而导致加工开裂现象。本文在晶体生长形貌及生长习性理论指导下,使用提拉法并采用合适的晶体生长工艺生长得到?80 mm×50 mm质量优异完整不开裂的α-BBO晶体。α-BBO晶体呈现三方对称,晶体沿c轴等径方向显露出α相的三方锥面{1102}和六方柱面{1120},这样能够保持α相稳定至室温从而解决α-BBO晶体开裂的难题,而且晶面的存在能够大幅度消除晶体内部残余热应力。研究结果表明,生长的α-BBO晶体在200~2 200 nm具有高透过性及优异的晶体质量,在紫外高功率偏振激光器件中具有重要应用价值。

Abstract: The high-temperature phase α-BBO crystal is an ideal ultraviolet birefringent crystal, but residual stresses caused by phase transitions during its growth process can easily lead to cracking during machining. This paper reports the growth and optical properties of α-BBO crystals. The α-BBO crystals up to ?80 mm×50 mm with transparency and free inclusion were grown by Czochralski method, guided by the theory of crystal morphology and habits. The α-BBO crystal exhibits triangular symmetry, with the c-axis being surrounded by the trigonal pyramids {1102} and hexagonal prisms {1120} of the α phase. The crystal faces of α-BBO crystal can keep the α phase stable at room temperature and solve the problem of cracking of α-BBO crystals. Moreover, the existence of crystal faces can greatly eliminate the residual thermal stress in the crystal. The results show that the grown α-BBO crystals have high transmittance in the range from 200 nm to 2 200 nm and excellent quality, which has important application in ultraviolet high power polarized laser devices.
