ABSTRACT
Nonlinear optical (NLO) crystals can efficiently convert the frequency of common solid-state laser with fixed or limited wavelengths. Since the first observation of second-harmonic generation (SHG) phenomenon in the early 1960s, they have played an increasing role in the fields of laser spectra, precision measurements, and quantum information, as well as industrial laser processing, and so on. However, it is still challenging to rationally design and synthesize new NLO crystals.

ABSTRACT
The first noncentrosymmetric d0 TM fluoroantimonate, Cs6Sb4Mo3O5F26, has been achieved by substituting the d0 TM in centrosymmetric Cs8Sb4Nb5O5F35. Cs6Sb4Mo3O5F26 features a phase-matchable SHG response of about 72% of the commercial KDP. Its powder laser-induced damage threshold (133.5 MW/cm2) is about 33.4 times that of AGS (4.0 MW/cm2). -

ABSTRACT
Three polymorphisms and two-step phase transitions of LiCdBO3 were investigated by the combination of powder X-ray diffraction, thermal analysis experimental techniques and the first principles calculations for the first time. The SHG switching was also achieved with a NLO switching contrast of about 625, indicating the potential applications in the sensors and optoelectronics. -

ABSTRACT
The co-crystallization of telluric acid and iodate gives rise to two noncentrosymmetric crystals AIO3·H6TeO6 (A = Rb+, NH4+). They show different intensity of SHG responses due to the slight change of the orientation of [IO3] and [Te(OH)6] groups induced by different cations in A-site. -

ABSTRACT
It is still very challenging to realize accurate design and synthesis of second-order nonlinear optical (NLO) crystals and evaluate the overall performance of new ultraviolet NLO materials. We, from the perspective of microscopic crystal structure based on KBBF, elaborate the accurate design and synthesis of high-performance NLO materials and analyse which atoms and groups can be replaced.
