“…Crystals with second harmonic generation (SHG) effects in the field of nonlinear optics (NLO) hold significant importance, due to their ability to precisely manipulate light and generate coherent radiation at various wavelengths. This characteristic finds extensive applications in high-resolution microscopy imaging, precision manufacturing, lithography, and optical communication. − Consequently, the pursuit of frequency doubling crystals with exceptional performance has become a focal point for the scientific and application community. However, the commercial frequency doubling crystals are limited to minority examples, including AgGaS 2 (AGS), ZnGeP 2 (ZGP), LiB 3 O 5 (LBO), KH 2 PO 4 (KDP), KTiOPO 4 (KTP), KBe 2 BO 3 F 2 (KBBF), and β-BaB 2 O 4 (β-BBO). − Hence, primitive exploration of new frequency doubling crystal materials remains an urgent research task. − …”
