Due to the advantages of short wavelength and higher precision processing, deep ultraviolet lasers have application prospects in high-precision technical fields such as semiconductor lithography, laser photoelectron spectrometer, and laser cutting
.
In the 1790s, studies discovered magnesia ore containing both isolated borate ions and sulfate ions.
Luo Junhua's team, a researcher at the State Key Laboratory of Structural Chemistry ("Inorganic Photoelectric Functional Crystal Materials"), Fujian Institute of the Structure of Matter, Chinese Academy of Sciences, discovered a new type of boron sulfate compound LiRb 4 [B(SO 4 ) 4 ]
.
Non-linear optical tests show that the crystal has a frequency doubling effect equivalent to that of KH 2 PO 4 and can achieve phase matching at room temperature
