- LITHIUM NIOBATE CRYSTAL THINGS TO KNOW BEFORE YOU BUY

However, the type-I configuration was normally employed for wavelength tunability of SHG mainly because LN displays a significant thermo-optic birefringence using a value of about four × ten−5 K−1 at room temperature. Hence, a temperature transform on the system would result in a substantial variation in the material birefringence, which
