General Description
BBO Pockels Cells, developed by POC, are advanced laser devices designed using the transverse electro-optic effect. When voltage is applied to the BBO crystal, the refractive index changes, allowing modulation of the polarization state of transmitted light. This technology enables high-speed modulation and precise optical control, making BBO Pockels Cells an essential component for applications requiring fast switching and high damage thresholds.
With low ringing effects and customizable features, POC BBO Pockels Cells are engineered for optimal performance, ensuring a high single-pass transmission of up to 99%. The devices are available in multiple configurations to suit various operational needs, including water cooling for enhanced thermal dissipation.
By employing high-quality BBO crystals and leveraging state-of-the-art manufacturing techniques, POC ensures durability and efficiency in a wide wavelength range (1030–1064 nm and beyond).
Applications
- Q-Switching: Enables high-power pulsed laser operations for material processing and micromachining.
- Pulse Picking: Precisely selects specific pulses for laser diagnostics and time-resolved experiments.
- Regenerative Amplifiers: Provides efficient optical feedback for ultra-fast laser systems.
- Cavity Dumping: Optimizes energy output in laser cavities with rapid switching speeds.
