Laser Crystals and Components

Pockels Cells

Electro-optic crystal is the key component of the pockels cells, when a voltage is applied to the electro-optic crystals, phase delay is induced in transmitted light, polarization direction of the light can be controlled by applied voltage, actually pockels cells act like a voltage-controlled waveplate. Pockels cells can function as EO modulators and optical switches, and it is often used in the Q-switching lasers.

Hangzhou Shalom EO offers the pockels cells made from DKDP crystals, BBO crystals and LiNbO3 or MgO:LiNbO3 crystals. DKDP pockels cells has high damage threshold, large aperture, and is often used in medical, cosmetic and industrial lasers. Pockels cells made of BBO crystals is good choice for ultra-violet (UV) lasers, and BBO pockels cells are also excellent for the lasers with high pulse repetition rate. LiNbO3 pockels cell has a low cost and good transmission up to 3 micro, it is often used in the medical lasers, and MgO:LiNbO3 pockels cell has a better damage threshold. Shalom EO also offers the polished, coated DKDP, BBO and LiNbO3 crystals with Cr-Au electrodes which is ready for EO pockels cells applications.
