本文研究了中心波长为800nm的120fs脉冲激光辐照硼酸盐玻璃时产生的微晶分布。利用拉曼光谱研究了硼酸盐玻璃中生成的偏硼酸钡晶体的高温相和低温相的分布。结合微爆炸模型，认为激光辐照引起的键断裂是BBO晶体形成的根源。根据激光能量密度和冷却条件，分布机制进行了讨论。
This paper deals with the distribution of generated microcrystallites in borate glass irradiated by 120 fs laser pulses at a central wavelength of 800 nm. Raman spectroscopy is used to investigate the distribution of the high and low temperature phases of barium metaborate crystals generated in the borate glass. In combination with a microexplosion model, bond-breaking induced by laser irradiation is served as the origin of the formation of BBO crystals. Depending on the laser fluence and cooling conditions, the distribution mechanisms have been discussed.
