Ferroelectric domain phenomena and microdomain engineering in BaMgF4 single crystal

Formation mechanism of scattering centers in BaMgF4 single crystals

“…This value is remarkably lower than those for stoichiometric or congruent LiNbO 3 and LiTaO 3 , which clearly facilitates the process of periodic poling. Its refractive indices in the entire transparent range as well as its domain properties and microdomain engineering have been reported [6][7][8][9]. Moreover, a period of 6.6 mm and the generation of 396 nm laser light have been obtained [3].…”

Femtosecond Z-scan measurement of third-order nonlinear refractive indices of BaMgF4

“…Recently, the ferroelectric fluoride BaMgF 4 crystal has been found widely transparent from 125 nm to 13 m, 5 so that it is capable to be used in the VUV as well as midinfrared regions ͑MIRs͒. The ferroelectric properties 6,7 and the domain phenomena 8,9 have been deeply studied by researchers. Furthermore, the realization of the periodic domain reversal of the BaMgF 4 crystal 5,6,10 has also been demonstrated, indicating BaMgF 4 as the good candidate for the fabrication of VUV ASSLs by quasiphase-match ͑QPM͒ technique.…”
