Organic second-order nonlinear optical crystals: materials for terahertz

Optimization of Functional Building Blocks Generates a Substantial Improvement in Birefringence from Sn2OSO4 to Sn3O2(OH)(HSO4)

“…Optical crystal materials play a pivotal role in a multitude of cutting-edge technology applications, particularly in laser technology, and are often regarded as the cornerstone of the optoelectronics industry. − Among these materials, birefringent crystals stand out as highly significant linear optical materials, serving as the fundamental component in the production of optical isolators, optical modulators, polarization-splitter mirrors, and polarizers. Currently, researchers have synthesized and commercialized a plethora of birefringent crystals with exceptional properties, including YVO 4 , α-BaB 2 O 4 , CaCO 3 , and MgF 2 , among others.…”
