Even so, the sort-I configuration was frequently used for wavelength tunability of SHG because LN reveals a big thermo-optic birefringence which has a price of somewhere around 4 × 10−five K−1 at space temperature. Hence, a temperature improve from the machine would bring about a substantial variation in the material https://sergiofwihg.answerblogs.com/32638771/new-step-by-step-map-for-lithium-niobate-crystal
