ELECTRO-OPTIC MODULATORS

BBO Electro-Modulators(BBO EOM)

Electro optic effect is the change of refractive index of crystal under the action of electric field parallel to the optical axis of crystal. The change of refractive index is a linear function of applied voltage and depends on the direction and polarization of incident beam. The nonlinear crystals used to make pucker box include BBO, KDP, DKDP, LiNbO, LitaO, KTP, RTP ADP, etc. The BBO photoelectric crystal manufactured by CASTON has many significant advantages in temperature stability、 High average power handling、etc.
