科研团队发明了一种新型“非互易飞秒激光极化铁电畴”技术，将飞秒脉冲激光聚焦于材料“铌酸锂”的晶体内部，通过控制激光移动的方向，在晶体内部形成有效电场，实现三维结构的直写和擦除。这一新技术，突破了传统飞秒激光的光衍射极限，把光雕刻铌酸锂三维结构的尺寸，从传统的 1 微米量级（相当于头发丝的五十分之一），首次缩小到纳米级，达到 30 纳米，大大提高了加工精度。

The research team invented a novel non-reciprocal femtosecond laser polarization ferroelectric domain technology. The femtosecond pulse laser is focused on the inside of lithium niobate crystal. By controlling the direction of laser movement, an effective electric field is formed inside the crystal, and the 3D structure can be directly written and erased >u)ZT  
This new technology breaks through the optical diffraction limit of traditional femtosecond laser, and reduces the size of the three-dimensional structure of lithium niobate from the traditional 1 micron (equivalent to one-fiftieth of a human hair) to the nanoscale for the first time, reaching 30 nanometers, greatly improving the processing accuracy
