Nonlinear optical (NLO) crystals are pivotal in laser application technology, which can convert the laser frequency to generate coherent light in the deep-ultraviolet (deep-UV, wavelengthλ≤200 nm) to far-infrared spectral range, and widely used in solid-state system detection, tissue imaging, quantum information,and more [1]. To expand the diversity of optical functional units and then discover novel NLO materials.
