Structural characteristics and second order nonlinear optical properties of borate crystals
نویسنده
چکیده
From the chemical bond viewpoint, the second order nonlinear optical (NLO) responses of some typical borate crystals with various crystal structures have been quantitatively studied. The correlations between structural characteristics and second order NLO properties of selected borate crystals are discussed. Calculations show that the isolated BO3 infrastructure is advantageous for borate crystals with large NLO responses. On the contrary, borate crystals with the BO4 or BxOy infrastructure forming various six-member B–O rings may be expected to be materials with smaller NLO responses. OCIS codes: (160.4330) Nonlinear optical materials; (190.2620) Frequency conversion.

Borates have long been recognized as a very important family of nonlinear optical (NLO) crystals, and have been widely used in the laser frequency-converting technology in ultraviolet (UV) and deep-ultraviolet (DUV) regions. In this work, the borate-based UV and DUV NLO crystals discovered in the recent decade are reviewed, and the structure–property relationship in the representative borate-ba...
