Elliptically Polarized

Principle of polarization encoding based on electro-optic effect of LiNbO3 crystal is analyzed, effact on polarization encoding optical field effects is studied when the incident light direction changes. Theoretical calculations show that, with the angle between the direction of incident laser beam and the main axis of LiNbO3 crystal increases, rotation angle of polarization ellipse remain unchanged,but ellipticity changes at any other position except in the center of the encoder,at the top and bottom of encoder,polarization state changes from circularly polarized to elliptically polarized,at other position of the encoder, polarization states are still elliptically polarized light but with different ellipticity angle. Experiment measurement results are in accord with ones of the calculation.

Thz Power

Generation of efficient terahertz (THz) pulses was experimentally made by tilted pump pulse front scheme with a Mg-doped LiNbO3 crystal. In this study, a spitfire laser (Ti:sapphire laser, 800 nm, 3 mJ, 1 kHz) was used as an optical source for the generation and detection of THz pulses. The electro-optic (EO) detection optics consisting of a ZnTe crystal (1 mm in thickness) and a balanced photodetector was used. To obtain optimum THz characteristics and pump to THz power conversion efficiency, the image of the grating was made coincides with the tilted pump pulse front. The maximum THz electric field of 8.5 kV/cm and the frequency bandwidth of 2.5 THz were achieved by using pump pulse energy of 2.4 mJ and pump pulse width of 100 fs. The THz energy of 4.15 μJ was obtained and pump-to-THz conversion efficiency was estimated to be approximately 1.73 x 10-3.
