Tsoelo-pele ea Lipatlisiso ea Likristale tsa Electro-Optic Q-Switched - Karolo ea 7: LT Crystal

Sebopeho sa kristale sa lithium tantalate (LiTaO3, LT for short) e ts'oana le kristale ea LN, e leng ea cubic crystal system, 3m sehlopha sa lintlha, R3c sehlopha sa sebaka. Kristale ea LT e na le lisebelisoa tse ntle tsa piezoelectric, ferroelectric, pyroelectric, acousto-optic, electro-optic le nonlinear optical properties. kristale ea LT e boetse e na le thepa e tsitsitseng ea 'mele le ea lik'hemik'hale, ho bonolo ho e fumana ka boholo bo boholo le boleng bo phahameng ba kristale e le' ngoe. Moeli oa eona oa tšenyo ea laser o phahame ho feta kristale ea LN. Kahoo kristale ea LT e 'nile ea sebelisoa haholo lisebelisoa tsa maqhubu a holimo.

 Likristale tsa LT tse sebelisoang ka tloaelo, joalo ka likristale tsa LN, li holisoa habonolo ke ts'ebetso ea Czochralski ka platinum kapa iridium crucible ho sebelisa karo-karolelano ea khaello ea lithium ea motsoako o tiileng oa metsi. Ka 1964, kristale e le 'ngoe ea LT e ile ea fumanoa ke Bell Laboratories,' me ka 2006, kristale ea LT e bophara ba 5-inch e ile ea lengoa ke Ping Kang.le al.

 Ts'ebetsong ea electro-optic Q-modulation, kristale ea LT e fapane le kristale ea LN ka hore γ ea eona.22 e nyane haholo. Haeba e amohela mokhoa oa ho fetisa khanya ka har'a axis ea optical le transverse modulation e ts'oanang le kristale ea LN, matla a eona a sebetsang a feta makhetlo a 60 a kristale ea LN tlasa boemo bo tšoanang. Ka hona, ha kristale ea LT e sebelisoa e le electro-optic Q-modulation, e khona ho amohela sebopeho sa kristale habeli se ts'oanang le kristale ea RTP e nang le x-axis e le leseli le y-axis joalo ka tataiso ea tšimo ea motlakase, 'me e sebelisa electro-optic ea eona e kholo. coefficient γ33 le γ13. Litlhoko tse phahameng tsa boleng ba optical le machining ea likristale tsa LT li fokotsa ts'ebeliso ea eona ea electro-optic Q-modulation.
