Pockels Cells

Pockels cells are electo-optic devices which function through the Pockels Effect, where 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. Because their switching behavior largely depends on the drive electronics, Pockels cells offer a much faster response time than acousto-optic devices. , actually pockels cells act like a voltage-controlled waveplate. Pockels cells can be applied 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.  

 The characteristics of DKDP crystal that it is easier to obtain large pieces of high quality single crystals , and it has good transmittance to visible light and have high damage threshold , the Pockels cells made by DKDP have large aperture and high damage tolerance 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 high power lasers with high pulse repetition rate.

LiNbO3 pockels cell is chemically stable and has a low cost and good transmission up to 3 micro, with high electro-optical coefficients.It is often used in the medical lasers. In comparison to the latter, MgO:LiNbO3 pockels has a better damage threshold than LiNbO3.

Hangzhou Shalom EO offers the off-the-shelf and custom Pockels Cells with high damage threshold, low insertion loss and competitive price, a variety of substrate materials are available: DKDP, BBO, LiNbO3, MgO:LiNbO3 pockels cells. Shalom EO also offers the polished, coated DKDP, BBO and LiNbO3 crystals with Cr-Au electrodes which is ready for EO pockels cells applications.
