Nevertheless, the kind-I configuration was often used for wavelength tunability of SHG mainly because LN displays a significant thermo-optic birefringence which has a price of about 4 × ten−5 K−one at home temperature. So, a temperature adjust from the system would result in a considerable variation in the material birefringence, https://troymqroi.bloguetechno.com/helping-the-others-realize-the-advantages-of-lithium-niobate-crystal-67798505
