Nevertheless, the type-I configuration was generally used for wavelength tunability of SHG because LN reveals a big thermo-optic birefringence using a price of approximately 4 × 10−five K−1 at space temperature. As a result, a temperature improve from the system would bring about a substantial variation in the fabric birefringence, https://andrefuhte.bloggazzo.com/31648067/not-known-facts-about-lithium-niobate-crystal
