Based on the birefringence of the LiNbO3 (LN) crystal
it firstly designed a electro-optic Q-switching technique with a pre-deflection of LN crystal. This technique can optimize the structure of Q-switched laser oscillators. Then it analyzed the angle of the pre-deflection the LiNbO3 (LN) in theoretical and simulated the relationship between the angle and the length of the crystal. Finally
an experiment was done to confirm the design
and it successfully obtained the pulsed laser
whose pulse width was 15.76ns with a 108mJ energy.
