The particulars of the effect of focused femtosecond laser pulses on antimony silicate glass with the composition 25Sb₂O₃∙75SiO₂ % (molar content) in thermal and athermal regimes were studied. It was found that in contrast to quartz, alkali silicate, and some borosilicate glasses the birefringence of the form characteristic for the formation of nanogratings does not arise in the laser-modified zones of the studied glass. Weak birefringence with slow axis parallel to the polarization plane of the writing laser beam, accompanied by precipitation of crystalline phases, seemingly including the cubic modification of Sb₂O₃, arises in the modified zones under irradiation by 10⁶ pulses with energy > 100 nJ and repetition frequency 10 and 200 kHz.

飞秒激光改性锑硅酸盐玻璃的特点

研究了飞秒聚焦激光脉冲对热态和非热态下组成为25Sb ₂ O ₃ ∙75SiO ₂％（摩尔含量）的硅酸锑玻璃的影响。已经发现，与石英，碱金属硅酸盐和某些硼硅酸盐玻璃相比，在所研究的玻璃的激光改性区域中不会出现形成纳米光栅的形式特征的双折射。慢轴平行于写入激光束偏振面的弱双折射，伴随着结晶相的沉淀，似乎包括Sb ₂ O ₃的立方变体，在10 ⁶照射下在变质区产生 能量> 100 nJ，重复频率10和200 kHz的脉冲。
