Buying Electro-optic Q Switches

Your reliable partner for photonics innovations!

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.

Hangzhou Shalom EO offers standard and custom Pockes cells made of DKDP, BBO crystals and LiNbO₃ or MgO:LiNbO₃ crystals.

Shalom EO’s DKDP Pockels cells feature high deuteration (>98%), low capacitance and fast rise time, and high transmission, high extinction ratio, with a maximum aperture of 50 mm is available.

Shalom EO’s 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 high damage threshold, low insertion loss, high extinction ratio, minimal piezoelectric ringing, and competitive price. BBO Pockels cells with both single and double BBO crystal designs and low-voltage geometries are available upon request.

Hangzhou Shalom EO also offers polished and AR-coated DKDP, BBO and LiNbO₃ and MgO:LiNbO₃ crystals with Cr–Au electrodes which can be used as central components of 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.

Nonlinear crystals pioneers

RTP Q-switches are ideal for high-performance applications requiring superior damage threshold and temperature stability, such as military, aerospace and high-power scientific lasers. Key specifications:

• half-wave voltage 3.6 kV
• >35 dB extinction ratio
• up to 15 × 15 mm² aperture
• high damage threshold (>1 GW/cm²)
• wide temperature range (–50°C to 70°C)
• non-hygroscopic
• MHz repetition rates

Laserton offers electro-optic Q switches based on BBO Crystal Pockels cell with a thermally compensated double crystal design. It could handle high average powers better than either KD*P or LiNbO3. Operation wavelength range from the UV to about 2 µm. Widely used in medical and aesthetic laser system
