Photonics USA provides high-performance electro-optic components, including Pockels cells, polarizing windows, and drivers, at fast lead times. We offer customizable solutions tailored to your specific application needs, from laser Q-switching to optical switching and modulation.


Pockels cells are electro-optic devices that utilize high-quality nonlinear materials such as KDP, KD*P, BBO, and LiNbO₃ for precise control of light polarization. These cells play a crucial role in modulating the phase and polarization of light when subjected to an external electric field. Widely used in applications like Q-switching, optical modulation, and fast switching in lasers, Pockels cells are ideal for systems requiring rapid response times and high-speed modulation. Their performance is essential in scientific research, medical devices, telecommunications, and laser systems, where precision and reliability are critical to achieving optimal results.

Electro-optic drivers provide the precise voltage and current control necessary for operating Pockels cells and other electro-optic components. These drivers are designed to deliver stable and accurate high-voltage pulses, ensuring optimal switching performance and precise modulation. In applications requiring fine-tuned electro-optic switching—such as laser Q-switching, high-speed shutters, and pulse picking—electro-optic drivers are essential for achieving fast response times and high signal fidelity. These drivers are widely used in industries ranging from telecommunications to medical imaging and defense, where exacting performance is a necessity.

Polarizing windows are key components in optical systems, offering high extinction ratios that enhance the performance of electro-optic devices, including Pockels cells. These windows function by selectively transmitting light with a specific polarization while blocking or reflecting unwanted polarization states, ensuring optimal light control. Commonly used in conjunction with other electro-optic components, polarizing windows improve signal quality and reduce unwanted noise in complex optical setups. Their ability to enhance polarization purity makes them indispensable in precision applications like spectroscopy, laser modulation, and various industrial processes.
