Problems solved by technology

Although the crystal growth technology of these materials has become increasingly mature, there are still obvious shortcomings: such as expensive, low optical damage threshold, and can only work with single crystal materials, it is difficult to achieve optical integration
Although this compound has been reported for a long time, these reports have not involved further testing and research on the linear and nonlinear properties of crystals and its application in nonlinear optics.
