- LITHIUM NIOBATE CRYSTAL NO FURTHER A MYSTERY

Even so, the type-I configuration was typically utilized for wavelength tunability of SHG since LN displays a major thermo-optic birefringence with a worth of close to 4 × 10−5 K−one at area temperature. Hence, a temperature alter in the unit would lead to a substantial variation in the fabric birefringence, which consequently shifts the
