By applying electric field control to the electro-optic crystal, the refractive index of the electro-optic crystal in a certain direction can be changed, so that the Pockel unit of the electro-optic modulator can be used as a variable half wave plate to change the polarization state. The wave Kerr unit of the electro-optic modulator is placed between two vertical polarizers to realize light intensity modulation. Electro optic effect can be divided into transverse electro-optic effect and longitudinal electro-optic effect. In the transverse electro-optic effect, the propagation direction of light is perpendicular to the electric field, while in the longitudinal electro-optic effect, the propagation direction of light is parallel to the electric field.
CRYLINK’s pockels cells use protective windows with high-quality AR coating, which can ensure a high transmission rate and prolong the service life of the device.
The half-wave voltage of the longitudinal electro-optic effect is independent of crystal size, so it is difficult to realize high-frequency electro-optic modulation. The working principle of BBO pockels cells is based on transverse electro-optic effect, the half wave voltage can be reduced by changing the size of BBO crystal. Crylink can provide BBO pockels cells with different aperture and lengths, which can adapt to different environments. Due to its low ringing effect and high laser-damaged threshold, the maximum frequency of Crylink’s BBO pockels cells can reach 1MHz.
