- LITHIUM NIOBATE CRYSTAL - AN OVERVIEW

Even so, the kind-I configuration was generally utilized for wavelength tunability of SHG due to the fact LN displays a substantial thermo-optic birefringence by using a value of somewhere around 4 × ten−5 K−1 at space temperature. Consequently, a temperature modify of the product would cause a substantial variation in the material biref

In apply, γ is nonzero if the polarization states of light in a very laboratory reference body usually are not matched to your intrinsic principal axes in the crystal frame. To orient the two reference frames collectively, e.g. the vertically polarized mild in the laser about the optical table is parallel to during the crystal, we mount the nonlin
