Where to Buy Electro-optic Q Switches

Shalom EO offers Pockels cells made from DKDP, BBO crystals and LiNbO₃ or MgO:LiNbO₃ crystals.

Our DKDP Pockels cells feature high damage thresholds and can be operated in a wide spectral range from 0.3 to 1.1 μm. They are often used in medical, cosmetic and industrial lasers. Aperture sizes up to 50 mm are available.

Our LiNbO₃ and MgO:LiNbO₃ Pockels cells are excellent choices for ultraviolet (UV) lasers to infrared lasers with long operating wavelengths up to 4 μm. LiNbO₃ Pockels cells are specially preferable for Er:YAG, Ho:YAG and Tm:YAG lasers.

Our BBO Pockels cells have significant advantages in terms of laser power handling abilities, temperature stability, and substantial absence of the piezoelectric ringing effect. BBO Pockels cells are particularly suitable for high repetition rate lasers with frequency up to 1 MHz.

Hangzhou Shalom EO also offers polished and AR-coated DKDP, BBO and LiNbO₃ and MgO:LiNbO₃ crystals with Cr-Au electrodes used in EO or AO Pockels cells.

The G&H electro-optic Q-switch employs the highest optical quality lithium niobate available. The electro-optic effect of lithium niobate makes it extremely useful for Pockels cell Q-switching of several laser types including Nd:YAG, Nd:YALO, Nd:YLF and Er:YLF. Lithium niobate Q-switches are used in both military and commercial applications, including target designating, range finding, and ophthalmic surgery. Our crystals offer low loss, high contrast ratio, and low wavefront distortion, and are qualified for use at 300 MW/cm². The temperature-stable (TS and XTS) versions of our electro-optic LN Q-switches allow operation over a wide range of temperatures while maintaining excellent contrast ratio.

EKSMA Optics manufactures OEM type Q-switching kits for the laser cavities that include Pockels cells with DKDP, BBO, or RTP electro-optical crystals, high voltage Pockels cells drivers optimized for the specific laser operation parameters, and high voltage power supplies for Pockels cells drivers powering. The complete Q-switching components sets are tested and adjusted for the optimal operation before shipping to the customers.

GWU's portfolio of electro-optical devices can meet even demanding requirements. The BBO or KD^*P Pockels cells offer a high extinction ratio, fast switching capability and a high damage threshold. They can be configured in flexible design, either free-space or fiber-coupled. We also offer driver electronics.
