线偏振光在接近350k的温度下光晶化的Se薄膜可以产生双折射。双折射近似于0.1，约为六边形Se的1/10。x射线衍射研究表明，光热诱导双折射是由硒链分子的排列引起的。
Birefringence can be induced in Se films photocrystallized by linearly polarized light at similar to 350 K. The birefringence reaches similar to 0.1, which is approximately 1/10 of that in the hexagonal Se. X-ray-diffraction investigations suggest that the photothermally induced birefringence is caused by alignment of Se chain molecules.
